Subject: [PATCH 6/6] leds: pca963x: Remove whitespace and checkpatch problems
This patch does some whitespace fixing to make the entire driver more
consistent, especially with regards to alignment. Because of this it
also reduces quite some of the checkpatch warnings.
Two slightly 80 char warnings remain however to satisfy the alignment
check.
This patch does not introduce any binary changes.
