As a result of the execution of the inner while loop, the value
of 'idx' can be equal to LINK_QUAL_MAX_RETRY_NUM. However, this
is not checked after the loop and 'idx' is used to write the
LINK_QUAL_MAX_RETRY_NUM size array 'lq_cmd->rs_table[idx]' below
in the outer loop.
The fix is to check the new value of 'idx' inside the nested loop,
and break both loops if index equals the size. Checking it at the
start is now pointless, so let's remove it.

Syzbot reported use-after-free Read in ath9k_hif_usb_rx_cb() [0]. The
problem was in incorrect htc_handle->drv_priv initialization.
Probable call trace which can trigger use-after-free:
ath9k_htc_probe_device()
/* htc_handle->drv_priv = priv; */
ath9k_htc_wait_for_target() <--- Failed

...
ath9k_hif_usb_rx_cb()
ath9k_hif_usb_rx_stream()

In order to not add fancy protection for drv_priv we can move
htc_handle->drv_priv initialization at the end of the
ath9k_htc_probe_device() and add helper macro to make
all *_STAT_* macros NULL safe, since syzbot has reported related NULL
deref in that macros [1]

Commit 680532c50bca ("drm: adv7511: Add support for
i2c_new_secondary_device") allows a device tree node to override
the default addresses of the secondary i2c devices. This is useful
for solving address conflicts on the i2c bus.
In adv7511_init_cec_regmap() the new i2c address of cec device is
read from device tree and immediately accessed, well before it is
written in the proper register to override the default address.
This can cause an i2c error during probe and a consequent probe
failure.
Once the new i2c address is read from the device tree, override
the default address before any attempt to access the cec.
Tested with adv7533 and stm32mp157f.

In the dsi_enable function, mtk_dsi_rxtx_control is to

MIPI should also be pulled down by writing a register
instead of disabling dsi.
If disable dsi without pulling the mipi signal low, the value of
the register will still maintain the setting of the mipi signal being

After resume, even if the mipi signal is not pulled high, it will still
be in the high state.

1) There is no need to check "buffer" for NULL. That's handled by
copy_from_user().
2) The "h2c_len" variable cannot be negative because it is unsigned

[ Upstream commit 8478095a8c4bcea3c83b0767d6c9127434160761 ]
The TC358767/TC358867/TC9595 are all capable of operating in multiple
modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Only the first mode is
currently supported. In order to support the rest of the modes without
making the tc_probe() overly long, split the bridge endpoint parsing
into dedicated function, where the necessary logic to detect the bridge
mode based on which endpoints are connected, can be implemented.

introduce a macro that takes the hwpwm id as parameter.

PWM_SIFIVE_SIZE_PWMCMP is easier to read, so define the offset macro
without the constant. The latter can then be dropped as there are no

[ Upstream commit 92f2b8bafa3d6e89c750e9d301a8b7ab76aaa8b6 ]
The arm_spe_pmu driver will enable SYS_PMSCR_EL1.CX in order to add CONTEXT
packets into the traces, if the owner of the perf event runs with required
capabilities i.e CAP_PERFMON or CAP_SYS_ADMIN via perfmon_capable() helper.
The value of this bit is computed in the arm_spe_event_to_pmscr() function
but the check for capabilities happens in the pmu event init callback i.e
arm_spe_pmu_event_init(). This suggests that the value of the CX bit should
remain consistent for the duration of the perf session.
However, the function arm_spe_event_to_pmscr() may be called later during
the event start callback i.e arm_spe_pmu_start() when the "current" process
is not the owner of the perf session, hence the CX bit setting is currently
not consistent.
One way to fix this, is by caching the required value of the CX bit during
the initialization of the PMU event, so that it remains consistent for the
duration of the session. It uses currently unused 'event->hw.flags' element
to cache perfmon_capable() value, which can be referred during event start
callback to compute SYS_PMSCR_EL1.CX. This ensures consistent availability
of context packets in the trace as per event owner capabilities.
Drop BIT(SYS_PMSCR_EL1_CX_SHIFT) check in arm_spe_pmu_event_init(), because
now CX bit cannot be set in arm_spe_event_to_pmscr() with perfmon_capable()
disabled.

[ Upstream commit 58577966a42fc0b660b5e2c7c9e5a2241363ea83 ]
Currently the DT for QCS404 SoC has setup for 2 USB2 PHYs with one each
assigned to USB3 controller and USB2 controller. This assignment is
incorrect which only works by luck: as when each USB HCI comes up it
configures the *other* controllers PHY which is enough to make them
happy. If, for any reason, we were to disable one of the controllers then
both would stop working.
This was a difficult inconsistency to be caught which was found while
trying to enable USB support in u-boot. So with all the required drivers
ported to u-boot, I couldn't get the same USB storage device enumerated
in u-boot which was being enumerated fine by the kernel.
The root cause of the problem came out to be that I wasn't enabling USB2
PHY: "usb2_phy_prim" in u-boot. Then I realised that via simply disabling
the same USB2 PHY currently assigned to USB2 host controller in the
kernel disabled enumeration for USB3 host controller as well.
So fix this inconsistency by correctly assigning USB2 PHYs.

The bananapi R64 (BPI-R64) experiences wrong WPS button signals.
In OpenWrt pushing the WPS button while powering on the device will set
it to recovery mode. Currently, this also happens without any user
interaction. In particular, the wrong signals appear while booting the
device or restarting it, e.g. after doing a system upgrade. If the
device is in recovery mode the user needs to manually power cycle or
restart it.
The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in
the device tree. This setting seems to suppress the unwanted WPS button
press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to
GPIO_ACTIVE_LOW.
