Rafael J. Wysocki e8b364b88c PM / Clocks: Do not acquire a mutex under a spinlock ... Commit b7ab83e (PM: Use spinlock instead of mutex in clock management functions) introduced a regression causing clocks_mutex to be acquired under a spinlock. This happens because pm_clk_suspend() and pm_clk_resume() call pm_clk_acquire() under pcd->lock, but pm_clk_acquire() executes clk_get() which causes clocks_mutex to be acquired. Similarly, __pm_clk_remove(), executed under pcd->lock, calls clk_put(), which also causes clocks_mutex to be acquired. To fix those problems make pm_clk_add() call pm_clk_acquire(), so that pm_clk_suspend() and pm_clk_resume() don't have to do that. Change pm_clk_remove() and pm_clk_destroy() to separate modifications of the pcd->clock_list list from the actual removal of PM clock entry objects done by __pm_clk_remove().
