[ Upstream commit 4ec7cece87b3ed21ffcd407c62fb2f151a366bc1 ]
Otherwise we can get:
WARNING: CPU: 0 PID: 55 at drivers/net/wireless/ti/wlcore/io.h:84
I've only seen this few times with the runtime PM patches enabled so this one is probably not needed before that. This seems to work currently based on the current PM implementation timer. Let's apply this separately though in case others are hitting this issue.
