mfd: ab8500-debugfs: Prevent initialised field from being over-written
Due to the lack of parity in the way array fields have been named/ numbered, a mistake was made where more debug fields were declared than actually existed. In doing so, 2 fields were added, which although unclear, were already declared in the array. The result was that the latter declarations trashed the former ones. This patch places the array back in the correct order and removes the offending NULL entries. While we're at it, let's ensure this doesn't happen again by naming each field properly and add a new *_LAST define to describe how many fields there should be. Signed-off-by: Lee Jones <lee.jones@linaro.org>
