[PATCH 0/2 v5.10-v6.1] Fix CVE-2025-22022

by Shivani Agarwal

To fix CVE-2025-22022, commit bb0ba4cb1065 is required; however, it depends on commit 7476a2215c07. Therefore, both patches have been backported to v5.10-v6.1.

[PATCH v2 4/5] media: ipu-bridge: Add DMI quirk for Dell XPS laptops with upside down sensors

by Hans de Goede

The Dell XPS 13 9350 and XPS 16 9640 both have an upside-down mounted OV02C10 sensor. This rotation of 180° is reported in neither the SSDB nor the _PLD for the sensor (both report a rotation of 0°). Add a DMI quirk mechanism for upside-down sensors and add 2 initial entries to the DMI quirk list for these 2 laptops. Note the OV02C10 driver was originally developed on a XPS 16 9640 which resulted in inverted vflip + hflip settings making it look like the sensor was upright on the XPS 16 9640 and upside down elsewhere this has been fixed in commit 69fe27173396 ("media: ov02c10: Fix default vertical flip"). This makes this commit a regression fix since now the video is upside down on these Dell XPS models where it was not before.

[PATCH] ALSA: hda/tas2781: Skip UEFI calibration on ASUS ROG Xbox Ally X

by Matthew Schwartz

According to TI, there is an issue with the UEFI calibration result on some devices where the calibration can cause audio dropouts and other quality issues. The ASUS ROG Xbox Ally X (RC73XA) is one such device. Skipping the UEFI calibration result and using the fallback in the DSP firmware fixes the audio issues.

[PATCH 0/7] clk: qcom: gcc: Do not turn off PCIe GDSCs during gdsc_disable()

With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This can happen during scenarios such as system suspend and breaks the resume of PCIe controllers from suspend. So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs during gdsc_disable() and allow the hardware to transition the GDSCs to retention when the parent domain enters low power state during system suspend.
