Subject: [media] lirc_dev: fix error return value
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b408809487e0b80fdd7869f92b5ca3be55923e9d;p=linux-beck.git

[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.
