From 2af86f9d954ee86e9b1c492e025de37a1b6d2db8 Mon Sep 17 00:00:00 2001 From: Karthik D A Date: Fri, 15 Jul 2016 18:18:39 +0530 Subject: [PATCH] mwifiex: Fix request_irq() failure handling It's been observed that request_irq() failure leads to a system crash due to a bug in mwifiex driver. When this failure happens, mwifiex_add_card() already takes care of clearing and freeing adapter->card pointer. This patch removes the redundant cleanup code causing crash.
