Using pr_crit in an header results in funny messages. Consider
#define pr_fmt(fmt) "mydriver: " fmt
#include <linux/hardirq.h>
which makes the message from ack_bad_irq
mydriver: unexpected IRQ trap...
so better use plain printk with KERN_CRIT directly.
This fixes a build problem on m68k with aufs3 en passant because the
latter builds with
ccflags-y +=
-D'pr_fmt(fmt)=AUFS_NAME"\040%s:%d:%s[%d]:\040"fmt,__func__,__LINE__,current->comm,current->pid'
without providing AUFS_NAME early enough for ack_bad_irq (which is the
problem of aufs).
