Subject: gpiolib: cdev: remove pointless decrement of i
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0cdc85a371c7c612a6fd04dd486a60f58350505b;p=linux.git

gpiolib: cdev: remove pointless decrement of i

Remove pointless decrement of variable, and associated comment.

While i is used subsequently, it is re-initialized so this decrement
serves no purpose.
