Subject: media: s5p-jpeg: Constify struct v4l2_m2m_ops Author: Rikard Falkeborn <[email protected]> Date: Tue Nov 30 22:27:00 2021 +0100 The only usage of the v4l2_m2m_ops structs is to pass their address to v4l2_m2m_init() which takes a pointer to const struct v4l2_m2m_ops as argument. Make them const to allow the compiler to put them in read-only memory.
