Subject: ide: sanitize ide_end_rq()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=37245aabfa0c628ba884cd88fe5cd633b426a1b2;p=linux-beck.git

ide: sanitize ide_end_rq()

* Move 'uptodate' quirk from ide_end_rq() to its users.

* Move quirks for blk_noretry_request() and !blk_fs_request()
  requests from ide_end_rq() to ide_end_request().

There should be no functional changes caused by this patch.
