Subject: [PATCH] cdrom/gdrom: Fix build error

Commit 7ae24fcee992 ("cdrom: remove the unused mode argument to
cdrom_release") was supposed to remove an unused argument from
cdrom_release(). but instead removed a used argument from
cdrom_open(). This results in the following build error.

drivers/cdrom/gdrom.c: In function 'gdrom_bdops_open':
drivers/cdrom/gdrom.c:484:15: error: too few arguments to function 'cdrom_open'

drivers/cdrom/gdrom.c: In function 'gdrom_bdops_release':
drivers/cdrom/gdrom.c:492:35: error: 'mode' undeclared

Fix it up.

My apologies for the noise if this has already been submitted.
If so I didn't find it. Also apologies for the wide distribution,
but the file doesn't seem to have a maintainer and I have no idea
who would/should apply the patch.
