[PATCH 2/2] char: genrtc: replace blacklist with whitelist

From: Arnd Bergmann
Date: Wed Mar 02 2016 - 04:49:47 EST


Every new architecture has to add itself to the growing list of those
that do not support the old "generic" RTC driver.

This replaces the long list of architectures that don't support it
with a shorter list of those that do.

The list is taken from those architectures that have a non-empty
asm/rtc.h header file and were not explicitly blacklisted.
