Subject: [PATCH V2 6/14] sony-laptop: new sony_nc_handles_resume function
Date: Fri, 09 Sep 2011 18:49:33 +0200	[thread overview]
Message-ID: <1315586973.3613.89.camel@vesuvio> (raw)
In-Reply-To: <1315585214.3613.51.camel@vesuvio>

New SNC resume function (sony_nc_handles_resume) for better event and
handle re-initialization called by sony_nc_resume, now pushed downwards
near sony_nc_add and sony_nc_cleanup for better readability and fewer
function prototypes.
