[media] af9035: override tuner for AVerMedia A835B devices
Original commit itself is correct, but it was replaced by more
general solution (commit 1cbbf90d04).
This old solution was committed by a accident and is not needed
anymore.

Old IT9135 AX needs a little bit different register settings for
sleep than newer IT9135 BX. This has been broken always, as power
management of the whole driver, but it started to be problem as I
fixed clock. Earlier clock was disabled very first on sleep and
rest of the commands were skipped by the chip as no clock, leaving
tuner full power state. When I fixed clocks these PM bugs started
raising out as I/O errors.

IT913x tuner driver disables own clock, provided by demod core, as
very a first operation when tuner is put on *sleep*. That likely
causes failure of all the rest commands on sleep sequence, which
leads situation where tuner is not actually on sleep, but consuming
a lot of power.
I measured 102mA current consumption from the USB before change
and after change it was only 32mA. Used device was single tuner
IT9135 BX.
Second reason to remove that register from tuner driver is reason
it is simply on wrong driver (demod vs. tuner), breaking the
principle of correct driver.
Clock is now provided more correctly af9033 demod driver as a
config option.

Integrated RF tuner of IT9135 is connected to demod clock source
named dyn0_clk. Enable that clock source in order to provide stable
clock early enough.

AF903x/IT913x demod provides clock source(s). It seems that this
clock source is used for integrated RF tuner of IT913x. It is
enabled by default, but firmware disables it automatically when
suspend is requested (suspend_flag (0x004c) + trigger_ofsm
(0x0000)). Automatic disable behavior seems to be similar for both
AF903x and IT913x I tested, though there is no likely any real
clock user in a case of AF903x.

Instead of sending command 13 to the tuner, send command 16 when sleeping. This
behaviour is observed when using manufacturer provided binary-only Linux driver
for TechnoTrend CT2-4400 (Windows driver does not do power management).
The issue with command 13 is that firmware loading is necessary after that.
This is not an issue with tuners that do not require firmware, but starting
streaming after sleep on an Si2158 takes noticeable time as firmware is
loaded on resume.

This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.
The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.
Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.
My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.
This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

Hi,
The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.
I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.

Old code in ehci-hcd tries to expedite disabling endpoints after the
controller has stopped, by destroying the endpoint's associated QH
without first unlinking the QH. This was necessary back when the
driver wasn't so careful about keeping track of the controller's
state.
But now we are careful about it, and the driver knows that when the
controller isn't running, no unlinking delay is needed. Furthermore,
skipping the unlink step will trigger a BUG() in qh_destroy() when the
preceding QH is released, because the link pointer will be non-NULL.
Removing the lines that skip the unlinking step and go directly to
QH_STATE_IDLE fixes the problem.

This is a set of three fixes. One represents a nasty shared tag map
regression (another inverted condition) caused by recent SCSI MQ patches, one
is a longstanding potential buffer overrun in the iscsi data buffer and the
final one is a use after free for the rare bidirectional commands.

...
When ending a bi-directionional SCSI request, blk_finish_request()
cleans up and frees the request, but scsi_release_bidi_buffers() tries
to indirect through the request to find it's data buffers. This causes
a panic due to a null pointer dereference.
Move the call to scsi_release_bidi_buffers() before the call to
blk_finish_request().
