H A D | irq-gic-v3.c | d102eb5c Fri Oct 14 02:26:21 CDT 2016 Dan Carpenter <dan.carpenter@oracle.com> irqchip/gicv3: Handle loop timeout proper
The timeout loop terminates when the loop count is zero, but the decrement of the count variable is post check. So count is -1 when we check for the timeout and therefor the error message is supressed.
Change it to predecrement, so the error message is emitted.
