[PATCH v2] [media] lirc_zilog: Clean up lirc zilog error codes

From: Yves Lemée
Date: Wed Jul 12 2017 - 15:17:50 EST


According the coding style guidelines, the ENOSYS error code must be returned
in case of a non existent system call. This code has been replaced with
the ENOTTY error code indicating a missing functionality.

v2: Improved punctuation
Fixed patch subject
