Subject: [PATCH] devfreq: add error check for sscanf in userspace governor

What this patch does:

	Current implementation of store_freq function in devfreq
	userspace governor executes further, even if error is returned
	from sscanf. This will result in setting up wrong frequency value.

	This patch adds proper error check to bail out if
	any error is returned.
