> These locks are not needed, why you want to have them arround?

Steffen I think you are being overly picky of Ben's changes.

I'd rather have too much locking during device probe and
initialization than a subtle bug that occurs because later on someone
decides to move IRQ enabling earlier in the chip init path and now
we get strange hangs that take forever to diagnose.

I mean, extra locking in probe/init paths... ugh, there are so many
more important things to worry about!

Once Ben posts a new version of this second patch with the
proper spin_lock_init() calls added I am going to apply both
of his changes.
