From b408809487e0b80fdd7869f92b5ca3be55923e9d Mon Sep 17 00:00:00 2001 From: Andi Shyti Date: Wed, 6 Jul 2016 06:01:24 -0300 Subject: [PATCH] [media] lirc_dev: fix error return value If ioctl is called, it cannot be a case of invalid system call number (ENOSYS), that is a ENOTTY case which means that the device doesn't support that specific ioctl command. So, replace ENOSYS with ENOTTY.
