Subject: lirc_serial: make checkpatch happy
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a6f6ad4173b31bb900d69689b6dfb0c01968abbd;p=linux-beck.git

lirc_serial: make checkpatch happy

There are a few checkpatch complains here. As we're about to
promote this driver out of staging, address them.
