Initialize local variable trans_support before it is used rather
than after. It is supposed to contain the value of a register on the
controller containing bits that describe which transport modes the
controller supports (e.g. "performant", "ioaccel1", "ioaccel2"). A

Without this, you'll see a null pointer dereference in
hpsa_enter_performant_mode().

So, I'm working on a block driver using the make_request_fn
interface, and have to handle a bio that comes in with
(bi_rw & REQ_FLUSH) set AND data to transfer.
