Subject: [PATCH] regulator: wm8350: fix missing increment of loop index i

From: Colin Ian King <colin.king@...onical.com>

It seems that the loop index i is not being incremented and hence
potentially the while loop could spin forever. Fortunately with the
data being used this does not appear to happen at the moment.
