[PATCH] [PATCH] drivers/misc: dummy-irq: use pr_* logging helpers

[a <osalexandeko@gmail.com>]

Replace printk(KERN_*) with pr_*() helpers for improved readability
and consistency with current kernel logging style.

Add pr_fmt() to avoid repeating module name in log messages.

No functional change intended.
