Subject: [git-or-PATCH] IRQ handler cleanups
This is the pure-cleanup stuff I pulled out of this morning's
remove-irq-arg work. No behavior changes, just killing dead code,
killing unused 'irq' arguments in sub-functions, and killing void*
casts.
Please pull from 'irqclean-submit1' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git irqclean-submit1
to receive the following updates:
