Thanks a lot for the clarification, I didn't know that.

I'll let the ChromiumOS folks to answer if EC connected through LPC will
only be used in x86 Chromebooks and non-x86 Chromebooks will always use
either SPI or I2C. Or if a non-x86 Chromebook with a EC connected through
LPC may exist in the future.
To know if I should either update the commit message or drop $subject,
since after patch 1/3 the driver builds correctly in other architectures.
