[PATCH] soundwire: fix pm_runtime_get_sync return code checks

When PM is disabled it returns -EACCES, which is currently threated as an error, and prevents accessing the slave's registers. This patch ignores the -EACCES return value from pm_runtime_get_sync() to let the SoundWire work in systems without runtime PM. Signed-off-by: Jan Kotas ---
