Subject: [PATCH 1/8] soundwire: intel_init: remove useless interrupt enablement in interrupt thread

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

When the code reaches the SoundWire interrupt thread handling, the
interrupt was enabled already, and there is no code that disables it
-> this is a no-op sequence.
