+description:
+  The MP8859 is a synchronous, 4-switch, integrated buck-boost converter
+  capable of regulating the output voltage from 2.8V to 22V wide input voltage
+  range with high efficiency.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
