Subject: [RFT][PATCH 2/2] spi: sirf: Add missing spi_master_{resume,suspend} calls to PM callbacks
Date: Wed, 05 Mar 2014 15:19:09 +0800 [thread overview]
Message-ID: <1394003949.18343.4.camel@phoenix> (raw)
In-Reply-To: <1394003843.18343.2.camel@phoenix>
This is required since commit 2025172e3280 "spi/bitbang: Use core message pump".
spi-bitbang now uses core message pump, so it needs to call spi_master_suspend/
spi_master_resume to stop/start the queue while suspend/resume.
