Subject: [PATCH] ASoC: cs35l56: Initialise a variable to silence possible static analysis error

From: Simon Trimmer <simont@...nsource.cirrus.com>

read_poll_timeout() is a macro and val will be populated before use,
however some static analysis tools treat it as a function and warn of
uninitialised variable usage.
