Subject: Re: [PATCH 4/7] drivers: leds: Add the iEi WT61P803 PUZZLE LED driver

Hello everyone,

I'm sending the email again, as I didn't send it as plain text
earlier, sorry.

Thanks for the comments, I'll review them and fix the issues.

This is currently the only iEi Puzzle series device that is using this
microcontroller. Their Intel-based platforms most likely will not use
this MCU, as they resorted to using more standard components there.

Some upcoming iEi Puzzle ARM-based boards might also implement this
microcontroller, so I do agree that using the new API would be beneficial
to future proof the driver.

Kind regards,
