 The code follows the 80 characters limitation yet tends to go 3 or 4 levels of
 indentation deep making it very unpleasant to read. This is specially relevant
 in the character driver ioctl code and in the core thread functions.

-* Fix behavior of message handling
-
-The polling behavior of vchiq_bulk_transmit(), vchiq_bulk_receive() and
-vchiq_queue_kernel_message() looks broken. A possible signal should be
-propagated back to user space to let the calling task handle it before
-retrying. Hopefully these msleep(1) shouldn't be necessary anymore.
