irqchip/mvebu-gicp: Use resource_size() for ioremap()
commit 9f7488f24c7571d349d938061e0ede7a39b65d6b upstream.
0-day reported an off by one in the ioremap() sizing:
drivers/irqchip/irq-mvebu-gicp.c:240:45-48: WARNING:
Suspicious code. resource_size is maybe missing with gicp -> res
Convert it to resource_size(), which does the right thing.
Fixes: 3c3d7dbab2c7 ("irqchip/mvebu-gicp: Clear pending interrupts on init")
Reported-by: kernel test robot <lkp@intel.com>
