Subject: staging: emxx_udc: add braces to if-else block
X-Git-Tag: v4.9-rc1~119^2~567
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3428e918e25611a08842b37b352ccb1960fbe012;p=karo-tx-linux.git

staging: emxx_udc: add braces to if-else block

add braces to if/else clause to fix the checkpatch issue braces {}
should be used on all arms of if/else block. Does not affect flow
because only single statement inside if/else block.
