From 655066c3835e7b51794c4d56f042eb78b5a79f53 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Date: Sun, 25 Jun 2006 05:48:17 -0700 Subject: [PATCH] RTC: rtc-dev UIE emulation Import genrtc's RTC UIE emulation (CONFIG_GEN_RTC_X) to rtc-dev driver with slight adjustments/refinements. This makes UIE-less rtc drivers work better with programs doing read/poll on /dev/rtc, such as hwclock. This emulation should not harm rtc drivers with UIE support, since rtc_dev_ioctl() calls underlaying rtc driver's ioctl() first.
