From 49bc52798d7bb66e958d7ea7378c38ec258b9037 Mon Sep 17 00:00:00 2001 From: Kent Gibson Date: Wed, 8 Jul 2020 12:15:48 +0800 Subject: [PATCH] gpiolib: cdev: rename 'filep' and 'filp' to 'file' to be consistent with other use Rename 'filep' and 'filp' to 'file' to be consistent with other use and improve readability.
