Subject: [PATCH] media: v4l2-compat-ioctl32.c: copy reserved2 field in get_v4l2_buffer32
Date: Fri, 17 Apr 2020 11:45:23 +0900 [thread overview]
Message-ID: <20200417024543.66785-1-sy0816.kang@samsung.com> (raw)
In-Reply-To: CGME20200417025205epcas2p46d33e64f2de49041d2ca68ecc98fc83e@epcas2p4.samsung.com
From: Sunyoung Kang <sy0816.kang@samsung.com>
get_v4l2_buffer32() didn't copy reserved2 field from userspace to driver.
So the reserved2 value is not received through compat-ioctl32 in driver.
This patch copy reserved2 field of v4l2_buffer in get_v4l2_buffer32().
