pinctrl: core: reset gpio_device in loop in pinctrl_pins_show()

2024-09-08T05:56:41+00:00

[ Upstream commit 9dfbcf2fc566c0be2de1c7685f29effd25696b75 ] We were not resetting the pointer to the associated gpio_device once we are done displaying a pin's information. This meant that once we reached the end of a gpio-range, if there were pins right after it that did not belong to any known range, they would be associated with the previous range's gpio device. This resulted in those pins appearing as <4294966783:old_gdev> instead of the expected <0:?> (due to gpio_num being -1).

media: uvcvideo: Enforce alignment of frame and interval

2024-09-08T05:56:40+00:00

[ Upstream commit c8931ef55bd325052ec496f242aea7f6de47dc9c ] Struct uvc_frame and interval (u32*) are packaged together on streaming->formats on a single contiguous allocation. Right now they are allocated right after uvc_format, without taking into consideration their required alignment. This is working fine because both structures have a field with a pointer, but it will stop working when the sizeof() of any of those structs is not a multiple of the sizeof(void*). Enforce that alignment during the allocation.

drm/amd/display: Disable DMCUB timeout for DCN35

2024-09-08T05:56:39+00:00

[ Upstream commit 7c70e60fbf4bff1123f0e8d5cb1ae71df6164d7f ] [Why] DMCUB can intermittently take longer than expected to process commands. Old ASIC policy was to continue while logging a diagnostic error - which works fine for ASIC without IPS, but with IPS this could lead to a race condition where we attempt to access DCN state while it's inaccessible, leading to a system hang when the NIU port is not disabled or register accesses that timeout and the display configuration in an undefined state. [How] We need to investigate why these accesses take longer than expected, but for now we should disable the timeout on DCN35 to avoid this race condition. Since the waits happen only at lower interrupt levels the risk of taking too long at higher IRQ and causing a system watchdog timeout are minimal.
