From: Anton Vorontsov Date: Fri, 4 Jul 2008 06:51:35 +0000 (-0700) Subject: [WATCHDOG] mpc8xxx_wdt: various renames, mostly s/mpc83xx/mpc8xxx/g X-Git-Tag: v2.6.27-rc3~81^2~6 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=59ca1b0d14ca71bdefef372ccd5035341e0ca091;p=linux-2.6 [WATCHDOG] mpc8xxx_wdt: various renames, mostly s/mpc83xx/mpc8xxx/g mpc83xx_wdt.c renamed to mpc8xxx_wdt.c, now we can do various renames in the file itself.
