Subject: bsg: Remove bogus check against request_queue->max_sectors
X-Git-Tag: MMI-PSA29.97-13-9~29228^2~4

bsg: Remove bogus check against request_queue->max_sectors

bsg submits REQ_TYPE_BLOCK_PC so the right check is max_hw_sectors.
But I've removed this check because right after, bsg proceeds with
calling blk_rq_map_user() which does all the right checks.
