Subject: pcmcia: cleanup/fixup patch for sa1100_jornada_pcmcia driver
From: Kristoffer Ericson <kristoffer.ericson@xxxxxxxxx>
Clean up the /drivers/pcmcia/sa1100_jornada.c file with respect to
formatting. It also changes a build warning into a code comment (since
its a pain to watch every build and havent seen any problems with driver
in 3.5years).
