Subject: media: hantro: Constify static struct v4l2_m2m_ops
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d47fed7a848718196c4e588178b8bcede5285f51;p=linux.git

media: hantro: Constify static struct v4l2_m2m_ops

The only usage of vpu_m2m_ops is to pass its address to v4l2_m2m_init()
which has a pointer to const struct v4l2_m2m_ops as argument. Make it
const to allow the compiler to put it in read-only memory.
