From 4c24e29e65843ed912c14cdc293ed922e33efdcc Mon Sep 17 00:00:00 2001 From: David Fries Date: Thu, 4 Oct 2012 17:14:12 -0700 Subject: rtc_sysfs_show_hctosys(): display 0 if resume failed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys contains a 1 (meaning "This rtc was used to initialize the system clock") even if setting the time by do_settimeofday() at bootup failed. The RTC can also be used to set the clock on resume, if it did 1, otherwise 0. Previously there was no indication if the RTC was used to set the clock in resume. This uses only CONFIG_RTC_HCTOSYS_DEVICE for conditional compilation instead of it and CONFIG_RTC_HCTOSYS to be more consistent. rtc_hctosys_ret was moved to class.c so class.c no longer depends on hctosys.c.
