Subject: [RESEND PATCH 08/11] soundwire: intel: remove useless readl

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

Cppcheck complains:

drivers/soundwire/intel.c:564:15: style: Variable 'link_control' is
assigned a value that is never used. [unreadVariable]
 link_control = intel_readl(shim, SDW_SHIM_LCTL);

This looks like a leftover from a previous version, remove.
