Subject: media: imx-jpeg: Constify static struct v4l2_m2m_ops
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=682e69d7a262d8959f8b8cc1a8ed68bc6ec4be61;p=linux.git

media: imx-jpeg: Constify static struct v4l2_m2m_ops

The only usage of mxc_jpeg_m2m_ops is to pass its address to
v4l2_m2m_init() which takes a pointer to const struct v4l2_m2m_ops. Make
it const to allow the compiler to put it in read-only memory.
