Subject: [PATCH 0/5] some smatch fixes
Date: Mon, 21 Jun 2021 13:56:44 +0200 [thread overview]
Message-ID: <cover.1624276137.git.mchehab+huawei@kernel.org> (raw)
This 5 patch series addresses a couple of other smatch warnings.
One of the patches seem to be fixing an user-visible bug:
media: uvc: don't do DMA on stack
Basically, input selection at the UVC driver seems broken, as it
is usind DMA on stack, which stopped working on Kernel 4.9.
In practice, the number of affected devices is probably small, as this
affects UVC devices with multiple inputs. The vast majority of UVC
ones have just one input.
Mauro Carvalho Chehab (5):
media: dib8000: rewrite the init prbs logic
media: uvc: don't do DMA on stack
media: v4l2-flash-led-class: drop an useless check
media: ivtv: prevent going past the hw arrays
media: sti: don't copy past the size
