From 98fcc5762dcecbb264fa4af5a9ae51136858e299 Mon Sep 17 00:00:00 2001 From: Micky Ching Date: Tue, 29 Apr 2014 09:54:54 +0800 Subject: mmc: rtsx: Revert "mmc: rtsx: add support for pre_req and post_req" This reverts commit c42deffd5b53c9e583d83c7964854ede2f12410d. commit did use mutex_unlock() in tasklet, but mutex_unlock() can't be used in tasklet(atomic context). The driver needs to use mutex to avoid concurrency, so we can't use tasklet here, the patch need to be removed. The spinlock host->lock and pcr->lock may deadlock, one way to solve the deadlock is remove host->lock in sd_isr_done_transfer(), but if using workqueue the we can avoid using the spinlock and also avoid the problem.
