mmc_request_done() is sometimes called from interrupt or other atomic context. Mostly all mmc_request_done() does is complete(), however it contains code to retry on error, which uses ->request(). As the error path is certainly not performance critical, this may be moved to the waiting function mmc_wait_for_req_done(). This allows ->request() to use runtime PM get_sync() and guarantee it is never in an atomic context. Signed-off-by: Adrian Hunter <adrian.hunter@xxxxxxxxx>
Calling back into the host driver directly from mmc_request_done when doing error handling were just plain wrong.
This patch is really great, not just for pm_runtime issues!
