From f8d2b9209ad648a8e9aa973d32fb64aa2ab01d00 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Mon, 14 Apr 2014 15:31:06 -0700 Subject: mwifiex: fix hung task on command timeout Sometimes when command timeout occurs due to a firmware or hardware bug, there may be some synchronous commands in command queue. These commands are never downloaded to firmware causing hung task warnings. This patch replaces wait_event_interruptible call with wait_event_interruptible_timeout to fix the issue.
