Subject: [PATCH AUTOSEL 5.1 136/219] media: vimc: cap: check v4l2_fill_pixfmt return value
Date: Mon, 15 Jul 2019 10:02:17 -0400	[thread overview]
Message-ID: <20190715140341.6443-136-sashal@kernel.org> (raw)
In-Reply-To: <20190715140341.6443-1-sashal@kernel.org>

From: André Almeida <andrealmeid@collabora.com>

[ Upstream commit 77ae46e11df5c96bb4582633851f838f5d954df4 ]

v4l2_fill_pixfmt() returns -EINVAL if the pixelformat used as parameter is
invalid or if the user is trying to use a multiplanar format with the
singleplanar API. Currently, the vimc_cap_try_fmt_vid_cap() returns such
value, but vimc_cap_s_fmt_vid_cap() is ignoring it. Fix that and returns
an error value if vimc_cap_try_fmt_vid_cap() has failed.
