drivers/media/platform/omap3isp/ispcsiphy.c: In function ‘csiphy_routing_cfg’: drivers/media/platform/omap3isp/ispcsiphy.c:71:57: warning: ‘shift’ may be used uninitialized in this function [-Wuninitialized] drivers/media/platform/omap3isp/ispcsiphy.c:40:6: note: ‘shift’ was declared here The warning is a false positive but the compiler is right in complaining. Fix it by using the correct enum data type for the iface argument and adding a default case in the switch statement.
