i2c: imx: match return type of wait_for_completion_timeout
return type of wait_for_completion_timeout is unsigned long not int. An appropriate variable of type unsigned long is introduced and the assignments fixed up. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
