md/raid5-ppl: Fix argument order in bio_alloc_bioset()
bio_alloc_bioset() takes a block device, number of vectors, the
OP flags, the GFP mask and the bio set. However when the prototype
was changed, the callisite in ppl_do_flush() had the OP flags and
the GFP flags reversed. This introduced some sparse error:
drivers/md/raid5-ppl.c:632:57: warning: incorrect type in argument 3
(different base types)
drivers/md/raid5-ppl.c:632:57: expected unsigned int opf
drivers/md/raid5-ppl.c:632:57: got restricted gfp_t [usertype]
drivers/md/raid5-ppl.c:633:61: warning: incorrect type in argument 4
(different base types)
drivers/md/raid5-ppl.c:633:61: expected restricted gfp_t [usertype]
gfp_mask
drivers/md/raid5-ppl.c:633:61: got unsigned long long
The sparse error introduction may not have been reported correctly by
0day due to other work that was cleaning up other sparse errors in this
area.
