Subject: [PATCH] drivers: pnp: proc.c: Removed unnecessary varibles
Date: Thu, 22 Apr 2021 23:33:22 +0530	[thread overview]
Message-ID: <20210422180322.7wlyg63kv3n2k6id@ubuntu> (raw)

[-- Attachment #1: Type: text/plain, Size: 1460 bytes --]

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.
