This one I have really tested properly and checked that the 'put' match the 'get's and that the device to regularly go to sleep as expected. NeilBrown From: NeilBrown Date: Thu, 26 Mar 2015 08:28:43 +1100 Subject: [PATCH] mmc: omap_hsmmc: stop using .enable and .disable method. enable and disable are only used to get and put runtime pm references. .set_ios already does this itself, and other drivers just do it in set_ios and .request without using enable/disable. So add pm_runtime get/put to omap_hsmmc_request(), and discard the enable/disable methods.
