Subject: [PATCH 12/15] lirc_dev: fix error return value
Date: Wed, 29 Jun 2016 22:20:41 +0900	[thread overview]
Message-ID: <1467206444-9935-13-git-send-email-andi.shyti@samsung.com> (raw)
In-Reply-To: <1467206444-9935-1-git-send-email-andi.shyti@samsung.com>

If ioctl is called, it cannot be a case of invalid system call
number (ENOSYS), that is an operation not permitted (EPERM).
Replace ENOSYS with EPERM.
