[ Upstream commit f3ca73862453ac1e64fc6968a14bf66d839cd2d8 ]
kernel test robot complains about a type mismatch:
block/blk-merge.c:984:42: sparse: expected restricted blk_opf_t const [usertype] ff
block/blk-merge.c:984:42: sparse: got unsigned int
block/blk-merge.c:1010:42: sparse: sparse: incorrect type in initializer (different base types) @@ expected restricted blk_opf_t const [usertype] ff @@ got unsigned int @@
block/blk-merge.c:1010:42: sparse: expected restricted blk_opf_t const [usertype] ff
block/blk-merge.c:1010:42: sparse: got unsigned int
because bio_failfast() is return an unsigned int rather than the
appropriate blk_opt_f type. Fix it up.
Fixes: 3ce6a115980c ("block: sync mixed merged request's failfast with 1st bio's")
