| |
2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Rajkumar Manoharan <rmanohar@qca.qualcomm.com>
commit c31eb8e926835582cd186b33a7a864880a4c0c79 upstream.
When no interface has been brought up, the chip's power state continued as AWAKE. So during resume, the chip never been powered up.
