Subject: rtc: hctosys: do not treat lack of RTC device as error
|
|
Origin: https://git.kernel.org/linus/aed98b9a1be6fcf1685dfd37f0a3e78e92a21f7d

Bug-Debian: https://bugs.debian.org/784146
|
|
|
|
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.
