[PATCH 7/8] cdrom/gdrom.c: handle add_disk() return value

From: Vishnu Pratap Singh
Date: Fri Nov 06 2015 - 07:38:16 EST

This patch handles add_disk() return value.
Earlier add_disk() function doesn't handle error
cases, now it is added, so the callers of this function
should also handle it.

Verfied on X86 based ubuntu machine.
This patch depends on [PATCH 1/8] block/genhd.c: Add error handling
