Subject: swim: clean up request completion paths
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e138b4e08ef65771000fbe6d93d67e3960ff862b;p=linux-beck.git

swim: clean up request completion paths

swim curiously tries to update request parameters before calling
__blk_end_request() when __blk_end_request() will do it anyway and
unnecessarily checks whether current_nr_sectors is zero right after
fetching.

Drop unnecessary stuff and use standard block layer mechanisms.

[ Impact: cleanup ]
