Subject: Re: [PATCH 1/2] tty: serial: samsung_tty: build it for any platform


Hi Greg,

samsung_tty driver is hardware specific driver so why should we
build it for any platform?

This change seems to defeat the whole purpose behind COMPILE_TEST
config option (which allows us to build hardware-specific drivers
without needlessly presenting the user with tons of non-relevant
config options).

Please explain this change some more, are you planing to remove
COMPILE_TEST config option?

Best regards,
