From 2343046826a8ca426b07601d9593ee046c298b68 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 8 May 2009 11:54:14 +0900 Subject: [PATCH] gdrom: dequeue in-flight request gdrom already dequeues and fully completes requests on normal path and the error paths can be easily converted to do so too. Clean it up and dequeue requests on error paths too. While at it remove superflous blk_fs_request() && !blk_rq_sectors() condition check.
