[PATCH 4/6] cdrom: introduce CDS_DRIVE_ERROR

From: Michal Suchanek
Date: Thu Dec 14 2017 - 10:14:56 EST


CDS_DRIVE_NOT_READY is used for the state in which CDROM is 'becoming
ready' (typically analyzing the disc) but also as the fallback when
nothing else applies. Introduce CDS_DRIVE_ERROR for the fallback case.
