[PATCH 2/2 v2] mfd: ab8500-core: Return zero in get_register_interruptible()

On Thu, 25 Oct 2018, Dan Carpenter wrote:

This function is supposed to return zero on success or negative error
codes on error.  Unfortunately, there is a bug so it sometimes returns
non-zero, positive numbers on success.

I noticed this bug during review and I can't test it.  It does appear
that the return is sometimes propogated back to _regmap_read() where all
non-zero returns are treated as failure so this may affect run time.

Fixes: 47c1697508f2 ("mfd: Align ab8500 with the abx500 interface")

v2: In v1, I introduced an new error path and forgot to drop the lock.
