No need for the { } brackets for a one-line if.

It also looks like a good idea if this check was just done in
blk_validate_limits() so that each driver doesn't have to do their own
checks. That block function is kind of recent though. Your patch here
looks fine if you want stable back-ports, but I haven't heard any
complaints till recently :)
