From: Hans Verkuil Date: Fri, 7 Mar 2014 10:28:39 +0000 (-0300) Subject: media: saa7134: fix WARN_ON during resume X-Git-Tag: v3.10.39~19 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6671cbfc06a126f21db1c1c3c7b38b9de2a0bfbf;p=platform%2Fkernel%2Flinux-3.10.git media: saa7134: fix WARN_ON during resume commit 30d652823de5fd7907d40e969a2d8e23938d8d03 upstream. Do not attempt to reload the tuner modules when resuming after a suspend. This triggers a WARN_ON in kernel/kmod.c:148 __request_module. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=69581. This has always been wrong, but it was never noticed until the WARN_ON was added in 3.9.
