[ridingqwerty]

Description

The initial submission of this board was incorrect. While it has 12 physical columns of keys, the wiring only utilizes 11 column pins. The layout in edc40.h and MATRIX_COLS in config.h have been amended to correct this.

It looks to me only the last commit is enough for what the description says.
Shouldn't you separately PR other 13 commits?
