Subject: [PATCH] rtc: s35390a: set uie_unsupported
|
|
Origin: https://git.kernel.org/linus/c0e12848be091e8410fb427f080f2e0149123443
|
|
Bug-Debian: https://bugs.debian.org/932845
|
|
|
|
Alarms are only supported on a per minute basis. This is why
|
|
uie_unsupported is set. Furthermore issue a warning when a second based
|
|
alarm is requested.
