PM: Do not acquire device semaphores upfront during suspend Remove the code that acquires all device semaphores from the suspend code path as it causes multiple problems to appear (most notably, http://bugzilla.kernel.org/show_bug.cgi?id=10030) and revert the change introduced by commit 4145ed6dc597a9bea5f6ae8c574653b2de10620f depending on the code being removed. Remove pm_sleep_lock()/pm_sleep_unlock() from device_add() to avoid the issue reported at http://bugzilla.kernel.org/show_bug.cgi?id=9874. It should fix the regreesions reported at: http://bugzilla.kernel.org/show_bug.cgi?id=9874 http://bugzilla.kernel.org/show_bug.cgi?id=10030 Signed-off-by: Rafael J.
