From 17e336db2b8ac5a91036184771655abe2d158273 Mon Sep 17 00:00:00 2001 From: Anupama K Patil Date: Thu, 22 Apr 2021 23:33:22 +0530 Subject: [PATCH] drivers: pnp: proc.c: Removed unnecessary varibles de, e are two variables of the type 'struct proc_dir_entry' which can be removed to save memory. This also fixes a coding style issue reported by checkpatch where we are suggested to make assignment outside the if statement.
