Subject: [PATCH 1/2] media: imx-jpeg: Constify static struct v4l2_m2m_ops
Date: Sat, 12 Jun 2021 01:42:00 +0200 [thread overview]
Message-ID: <20210611234201.64832-2-rikard.falkeborn@gmail.com> (raw)
In-Reply-To: <20210611234201.64832-1-rikard.falkeborn@gmail.com>
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.
