From 1ce7948fe18230ae096cdb78211715309de9889c Mon Sep 17 00:00:00 2001 From: Somya Anand Date: Mon, 9 Mar 2015 19:18:24 +0530 Subject: [PATCH] Staging: rtl8188eu: Remove redundant local variable This patch removes a redundant variable "val" and adds inline return statements. It also adds a default case to the switch statement which returns 0 to keep the logic intact. It also removes a redundant variable "inx" and adds inline return statements.
