Subject: ide: ide_lock + __blk_end_request() -> blk_end_request()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c8a2cce47c6813383c9e38134e31f7e5f72e9d8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ide: ide_lock + __blk_end_request() -> blk_end_request()

Use blk_end_request() instead of ide_lock + __blk_end_request()
in cdrom_end_request(), cdrom_newpc_intr(), __ide_end_request(),
ide_complete_pm_request() and ide_end_drive_cmd().

[ ide_lock is currently also used as queue lock ]
