Hi all,
This is truly untested. I only compile tested thus far
as I'm not sure it's the right path. It looks like that's

In a few minutes, I'll be starting to test these two

Hi all,
I dropped the twl6030-irq.c changes because that
thing is a bit messy. I hope the original author
will feel inspired and fix that one up.
Anyway, twl4030-irq.c seems to be going to the
right direction now. Thanks to Mark Brown for
pointing out the need to drop the locking and

Finally that workqueue isn't needed anymore.
Drop that hackery and move the spinlock_t to
a mutex so we can issue I2C operations with
a lock held.
