Subject: [PATCH] v4l-utils: use openat when available
Date: Tue, 22 Jan 2013 18:37:22 +0200	[thread overview]
Message-ID: <1358872642-30843-1-git-send-email-riku.voipio@linaro.org> (raw)

New architectures such as 64-Bit arm build kernels without legacy
system calls - Such as the the no-at system calls. Thus, use
SYS_openat whenever it is available.
