Subject: [PATCH] rtc: rtc-mc146818-lib: Use is_leap_year instead of calculate leap years
Date: Sun, 6 Oct 2024 09:15:53 +0900 [thread overview]
Message-ID: <20241006001553.7430-1-iwamatsu@nigauri.org> (raw)
The is_leap_year() for determining leap year is provided in rtc lib.
This uses is_leap_year() instead of its own leap year determination
routine.
