Subject: omap_serial: Removing superfluous check on no interrupt pending.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e60f9fd03b8b5323a8569abc23c62396e0dfa9ad;p=linux.git

omap_serial: Removing superfluous check on no interrupt pending.

The do .. while loop checks for interrupt pending at the
start of the loop and exits if there is none, it then
checks again for this condition at the end of the loop.
