media: mediatek: vcodec: Can't set dst buffer to done when lat decode error

2022-12-31T12:33:03+00:00

[ Upstream commit 3568ecd3f3a6d133ab7feffbba34955c8c79bbc4 ]

Core thread will call v4l2_m2m_buf_done to set dst buffer done for
lat architecture. If lat call v4l2_m2m_buf_done_and_job_finish to
free dst buffer when lat decode error, core thread will access kernel
NULL pointer dereference, then crash.

media: imx-jpeg: Disable useless interrupt to avoid kernel panic

2022-12-31T12:32:58+00:00

[ Upstream commit c3720e65c9013a7b2a5dbb63e6bf6d74a35dd894 ]

There is a hardware bug that the interrupt STMBUF_HALF may be triggered
after or when disable interrupt.
It may led to unexpected kernel panic.
And interrupt STMBUF_HALF and STMBUF_RTND have no other effect.
So disable them and the unused interrupts.

meanwhile clear the interrupt status when disable interrupt.

media: coda: Add check for kmalloc

2022-12-31T12:32:25+00:00

[ Upstream commit 6e5e5defdb8b0186312c2f855ace175aee6daf9b ]

As the kmalloc may return NULL pointer,
it should be better to check the return value
in order to avoid NULL poineter dereference,
same as the others.

media: c8sectpfe: Add of_node_put() when breaking out of loop

In configure_channels(), we should call of_node_put() when breaking
out of for_each_child_of_node() which will automatically increase
and decrease the refcount.

media: s5p-mfc: Add variant data for MFC v7 hardware for Exynos 3250 SoC

[ Upstream commit f50ebe10f5d8092c37e2bd430c78e03bf38b1e20 ]

Commit 5441e9dafdfc6dc40 ("[media] s5p-mfc: Core support for MFC v7")
which adds mfc v7 support for Exynos3250 and use the same compatible
string as used by Exynos5240 but both the IPs are a bit different in
terms of IP clock.
Add variant driver data based on the new compatible string
"samsung,exynos3250-mfc" for Exynos3250 SoC.
