Subject: [PATCH] i386 Remove useless code in tsc.c
X-Git-Tag: v2.6.21-rc1~155
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=26a08eb301a2e3fce5a501e3dd26cf3ec46591d7;p=linux-2.6-omap-h63xx.git

[PATCH] i386 Remove useless code in tsc.c

The delayed work code in arch/i386/kernel/tsc.c is an unused leftover of the
GTOD conversion. Remove it.
