This should be testing "regmap" instead of "priv->regmap". The
"priv->regmap" variable is always zero so it's not an error pointer.

The commit 106b104137fd ("counter: Add microchip TCB capture counter")
doesn't use the correct patch prefix. This is a common mistake for the
the first commit which adds the driver. There is no kernel wide
standard for patch prefixes so it's difficult for people sending fixes
to know the correct prefix should be.

Seems I applied this one a while back but never replied to this thread.
Sorry about that!
