gdrom: fix mistake in assignment of error

axboe · axboe · commit 0a40a9352473 · 2018-10-25T11:17:40.000-06:00
Apparently the kbuild bots missed this one originally, but at least it caught it now. Fix compilation error: All errors (new ones prefixed by >>): drivers/cdrom/gdrom.c: In function 'probe_gdrom': >> drivers/cdrom/gdrom.c:797:3: error: 'rc' undeclared (first use in this function) rc = PTR_ERR(gd.gdrom_rq); ^~ drivers/cdrom/gdrom.c:797:3: note: each undeclared identifier is reported only once for each function it appears in Fixes: ad5fc6b ("gdrom: convert to blk-mq") Signed-off-by: Jens Axboe <axboe@kernel.dk>
