Re: [PATCH v2 2/4] watchdog: orion: Use the reference clock on Armada 375 SoC

Dear Ezequiel Garcia,

It's really nitpicking, but I find the usage of empty newlines rather
unfortunate in the below function.

This empty new line seems not needed.

But one empty new line before the return would be good.

An empty newline would be good here as well.

And here.

With this fixed:
