Subject: staging: unisys: refactor pause_device()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=441a29a57e1d88a280308b860d57ac45bd77903a;p=linux-beck.git

staging: unisys: refactor pause_device()

Fix the function declaration so it is on a single line. Fix CamelCase local
variables:

busNo => bus_no
devNo => dev_no

Fix use of uuid_le_cmp() to check for 0 instead of using !uuid_le_cmp().
