[PATCH] USE_INTERNAL_TIMER explicitely #undef-ed and not in kconfig

From: Christoph Egger
Date: Fri Feb 05 2010 - 07:11:16 EST


CONFIG_USE_INTERNAL_TIMER seems to be the remainings of some
experiment. It is explicitely #undef-ed as not working, only
referenced from one source file and rather aged.

Hereby cleaning it from the kernel tree.
