From aed98b9a1be6fcf1685dfd37f0a3e78e92a21f7d Mon Sep 17 00:00:00 2001 From: Floris Bos Date: Thu, 16 Apr 2015 12:45:12 -0700 Subject: [PATCH] rtc: hctosys: do not treat lack of RTC device as error When using device trees on the ARM platform, it is not certain at compile time whether or not the system will have a RTC. If one enables CONFIG_HCTOSYS just in case the system booted has a RTC, and it turns out not to be, this will result in a big fat "unable to open rtc device" error being printed to console, even when "quiet" is set in the kernel cmdline. Fix this by outputting the message with loglevel info instead.
