Re: [PATCH v3 1/2] dt-bindings: input: Add Nuvoton MA35D1 keypad

Posted by Ming-Jen Chen 4 days, 10 hours ago

Hi:

I apologize for the oversight in my previous patch where I forget to 
include v3 in the subject line.

The content of the patch remains the same, only the version label has 
been corrected.
