Subject[PATCH 1/2] media: vicodec: constify v4l2_ctrl_ops structure
Date
The v4l2_ctrl_ops structure is only stored in the ops field of a
v4l2_ctrl_config structure, and this field is const, or passed as the
second argument of v4l2_ctrl_new_std, and the corresponding parameter
is declared as const. Accordingly, the structure can also be const.

Done with the help of Coccinelle.
