Subject: [PATCH] i2c: designware: fixup return handling of
 wait_for_completion_timeout

return type of wait_for_completion_timeout is unsigned long not int, rather
than introducing a new variable the wait_for_completion_timeout is moved
into the if condition as the return value is only used to detect timeout.
