From 71fc822455ccb63a66be0b6e97a415aceb0062c6 Mon Sep 17 00:00:00 2001 From: David Brownell <david-b@pacbell.net> Date: Wed, 23 Jul 2008 21:30:38 -0700 Subject: rtc: rtc-omap footprint shrinkage Shrink the runtime footprint of the OMAP1 RTC driver a bunch by removing some old hacks and switching to platform_driver_probe().
