From 91a5307cb0b164024725d68990441553740a2149 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 9 Aug 2014 21:47:20 -0300 Subject: [media] xc5000: fix xc5000 suspend After xc5000 stops working, it waits for 5 seconds, waiting for a new usage. Only after that it goes to low power mode. If a suspend event happens before that, a work queue will remain active, with causes suspend to crash.
