Subject: [PATCH v7 2/6] ivtv-ioctl.c: Do not initialize the reserved field of struct v4l2_fmtdesc
Date: Mon, 13 Apr 2020 22:23:47 +0200	[thread overview]
Message-ID: <20200413202351.1359754-3-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20200413202351.1359754-1-niklas.soderlund+renesas@ragnatech.se>

One of the reserved fields are about to be used. Instead of updating the
driver to only initialize three instead of four reserved fields remove
the explicit assignment.  As if one field in a struct is assigned, the
memory is zeroed and explicit assignment is redundant.
