kernel/irq/proc.c: In function ‘show_irq_affinity’: include/linux/cpumask.h:24:29: warning: ‘mask’ may be used uninitialized in this function [-Wmaybe-uninitialized] #define cpumask_bits(maskp) ((maskp)->bits) gcc is silly, but admittedly it can't know that this won't be called with anything else than the enumerated constants. Shut up the warning by creating a default clause. Fixes: 6bc6d4abd22e ("genirq/proc: Use the the accessor to report the effective affinity Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
