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

[Richard Fitzgerald]

From: Simon Trimmer <simont@xxxxxxxxxxxxxxxxxxxxx>

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.
