Subject: [PATCH] staging: media: rkvdec: Constify static struct v4l2_m2m_ops
Date: Wed, 13 Oct 2021 00:11:44 +0200	[thread overview]
Message-ID: <20211012221144.30638-1-rikard.falkeborn@gmail.com> (raw)

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.
