CVE-2023-52850

In the Linux kernel, the following vulnerability has been resolved: media:
hantro: Check whether reset op is defined before use The i.MX8MM/N/P does
not define the .reset op since reset of the VPU is done by genpd. Check
whether the .reset op is defined before calling it to avoid NULL pointer
dereference. Note that the Fixes tag is set to the commit which removed the
reset op from i.MX8M Hantro G2 implementation, this is because before this
commit all the implementations did define the .reset op.
