4e1dfb0035 cris: Only build flash rescue image if CONFIG_ETRAX_AXISFLASHMAP is selected
commit 328cf6927bb72cadefddebbc9a23c793108147a2 upstream.

If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image
object file is empty. With recent versions of binutils, this results
in the following build error.

cris-linux-objcopy: error:
	the input file 'arch/cris/boot/rescue/rescue.o' has no sections

This is seen, for example, when trying to build cris:allnoconfig
with recently generated toolchains.

Since it does not make sense to build a flash rescue image if there is
no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled.

15e0355a1e ath10k: use the right length of "background"
commit 31b239824ece321c09bdb8e61e1d14814eaba38b upstream.

The word "background" contains 10 characters so the third argument of
strncmp() need to be 10 in order to match this prefix correctly.

ac86312e08 mfd: tps65217: Fix page fault on unloading modules
commit 40a50f8b307de8d08f3fa37c312fc16a7dd233e5 upstream.

TPS65217 IRQ domain should be removed and initialised as NULL when the
module is unloaded for the next use. When tps65217.ko is loaded again,
it causes the page fault. This patch fixes the error below.

a24f1f3520 ath10k: fix failure to send NULL func frame for 10.4
commit fcf7cf1551cae54e747a771f5808240f2a37708f upstream.

This partially reverts 'commit 2cdce425aa33
("ath10k: Fix broken NULL func data frame status for 10.4")'
Unfortunately this breaks sending NULL func and the existing
issue of obtaining proper tx status for NULL function will be
fixed. Also update the comments for feature flag added to be
useless and not working

45816391e1 nl80211: Use different attrs for BSSID and random MAC addr in scan req
commit 2fa436b3a2a7009c11a3bc03fe0ff4c26e80fd87 upstream.

NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned
and the random MAC address to be used when privacy is enabled. When both
the features are enabled, both the BSSID and the local MAC address were
getting same value causing Probe Request frames to go with unintended
DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID
attribute to set the specific BSSID (which was the more recent addition
in cfg80211) for a scan.

Backwards compatibility with old userspace software is maintained to
some extent by allowing NL80211_ATTR_MAC to be used to set the specific
BSSID when scanning without enabling random MAC address use.

Scanning with random source MAC address was introduced by commit

cd84516473 mac80211: fix tid_agg_rx NULL dereference
commit 1c3d185a9a0b136a58e73b02912d593d0303d1da upstream.

On drivers setting the SUPPORTS_REORDERING_BUFFER hardware flag,
we crash when the peer sends an AddBA request while we already
have a session open on the seame TID; this is because on those
drivers, the tid_agg_rx is left NULL even though the session is
valid, and the agg_session_valid bit is set.

To fix this, store the dialog tokens outside the tid_agg_rx to
be able to compare them to the received AddBA request.

1d9c33f1b4 drm/i915: tune down the fast link training vs boot fail
commit 2c57b18adb93fc070039538f1ce375d3d3e99bbb upstream.

It's been unfixed since a while and no one is immediately working on
this. And we have the FIXME already. And now also a task in the DP
team's backlog.

8b4879154a drm/i915/dp: add lane_count check in intel_dp_check_link_status
commit d4cb3fd9b548b8bfe2a712ec920b9ebabd3547ab upstream.

Currently it's entirely possible to go through the link training step
without first determining the lane_count, which is silly since we end up
doing a bunch of aux transfers of size = 0, as highlighted by
WARN_ON(!msg->buffer != !msg->size), and can only ever result in a
'failed to update link training' message. This can be observed during
intel_dp_long_pulse where we can do the link training step, but before
we have had a chance to set the link params. To avoid this we add an
extra check for the lane_count in intel_dp_check_link_status, which
should prevent us from doing the link training step prematurely.

v2: add WARN_ON_ONCE and FIXME comment (Ville)

5af6f56bb1 usb: dwc3: gadget: always unmap EP0 requests
commit d62145929992f331fdde924d5963ab49588ccc7d upstream.

commit 0416e494ce7d ("usb: dwc3: ep0: correct cache
sync issue in case of ep0_bounced") introduced a bug
where we would leak DMA resources which would cause
us to starve the system of them resulting in failing
DMA transfers.

Fix the bug by making sure that we always unmap EP0
requests since those are *always* mapped.

Let's call dwc3_ep0_prepare_one_trb() explicitly

than one TRB to handle an EP0 transfer.

96a0c8ee7c iio: accel: st_accel: fix LIS3LV02 reading and scaling
commit 65e4345c8ef8811bbb4860fe5f2df10646b7f2e1 upstream.

The LIS3LV02 has a special bit that need to be set to get the
read values left aligned. Before this patch we get gibberish
like this:

iio_generic_buffer -a -c10 -n lis3lv02dl_accel
(...)
0.000000 -0.010042 -0.642688 19155832931907
0.000000 -0.010042 -0.642688 19155858751073

Which is because we read a raw value for 1g as 64 which is
the nominal 1024 for 1g shifted 4 bits to the left by being
right-aligned rather than left aligned.

Since all other sensors are left aligned, add some code to
set the special DAS (data alignment setting) bit to 1 so that
the right value is now read like this:

iio_generic_buffer -a -c10 -n lis3lv02dl_accel
(...)
0.000000 -0.147095 -10.120135 24761614364956
-0.029419 -0.176514 -10.120135 24761631624540

The scaling was weird as well: we have a gain of 1000 for 1g
and 3000 for 6g. I don't even remember how I came up with the
old values but they are wrong.

and OS1 pins are being set. Fix the typo to allow proper control of the

commit 7b01738112608ce47083178ae2b9ebadf02d32cc upstream.

This fixes a regression which was introduced by commit f1bddbb, by
reverting a small fragment of commit 855ed04.

If the following conditions were met, usb_gadget_probe_driver() returned
0, although the call was unsuccessful:
1. A particular UDC was specified by thge gadget driver (using member
"udc_name" of struct usb_gadget_driver).
2. The UDC with this name is available.
3. Another gadget driver is already bound to this gadget.
4. The gadget driver has the "match_existing_only" flag set.
In this case, the return code variable "ret" is set to 0, the return
code of a strcmp() call (to check for the second condition).

This also fixes an oops which could occur in the following scenario:
1. Two usb gadget instances were configured using configfs.
2. The first gadget configuration was bound to a UDC (using the configfs
attribute "UDC").
3. It was tried to bind the second gadget configuration to the same UDC
in the same way. This operation was then wrongly reported as being
successful.
4. The second gadget configuration's "UDC" attribute is cleared, to
unbind the (not really bound) second gadget configuration from the UDC.

DCFG.DEVSPD == 0x3 is not valid and we need to set
DCFG.DEVSPD to 0x1 for full speed mode. Same goes for
DSTS.CONNECTSPD.

Old databooks had 0x3 for full speed in 48MHz mode for
USB1.1 transceivers which was never supported. Newer databooks
don't mention 0x3 at all.

63d92d10a8 xhci: Fix race related to abort operation
commit 1c111b6c3844a142e03bcfc2fa17bfbdea08e9dc upstream.

Current abort operation has race.

    xhci_handle_command_timeout()
      xhci_abort_cmd_ring()
        xhci_write_64(CMD_RING_ABORT)
        xhci_handshake(5s)
	  do {
	    check CMD_RING_RUNNING
            udelay(1)
					 ...
					 COMP_CMD_ABORT event
					 COMP_CMD_STOP event
					 xhci_handle_stopped_cmd_ring()
					   restart cmd_ring
                                           CMD_RING_RUNNING become 1 again
	  } while ()
          return -ETIMEDOUT
        xhci_write_64(CMD_RING_ABORT)
        /* can abort random command */

To do abort operation correctly, we have to wait both of COMP_CMD_STOP
event and negation of CMD_RING_RUNNING.

But like above, while timeout handler is waiting negation of
CMD_RING_RUNNING, event handler can restart cmd_ring. So timeout
handler never be notice negation of CMD_RING_RUNNING, and retry of
CMD_RING_ABORT can abort random command (BTW, I guess retry of
CMD_RING_ABORT was workaround of this race).

To fix this race, this moves xhci_handle_stopped_cmd_ring() to
xhci_abort_cmd_ring().  And timeout handler waits COMP_CMD_STOP event.

At this point, timeout handler is owner of cmd_ring, and safely
restart cmd_ring by using xhci_handle_stopped_cmd_ring().

[FWIW, as bonus, this way would be easily extend to add CMD_RING_PAUSE
operation]

commit fde1faf872ed86d88e245191bc15a8e57368cd1c upstream.

A static usb-serial-driver structure that is used to initialise the
interrupt URB was modified during probe depending on the currently
probed device type, something which could break a parallel probe of a
device of a different type.

Fix this up by overriding the default completion callback for MCS7715
devices in attach() instead. We may want to use two usb-serial driver
instances for the two types later.
