Subject: [PATCH] staging: bcm2835-audio: use | instead of || otherwise result is just boolean 1

From: Colin Ian King <colin.king@...onical.com>

The incorrect or operator is being used resulting in cookies being
set to 1 (true) rather than the intended hex value.  Fix this by
using | instead of ||.

Issue found with static analysis with cppcheck
