X-Git-Tag: v6.1-rc5~2250^2~134
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=30162960165fe608f505d2564a9abc8514ffb7df;p=platform%2Fkernel%2Flinux-starfive.git

media: staging: media: rkvdec: Constify static struct v4l2_m2m_ops

The only usage of rkvdec_m2m_ops is to pass its address to v4l2_m2m_init(),
which takes a pointer to const v4l2_m2m_ops as argument. Make it const
to allow the compiler to put it in read-only memory.
