From 4e7a9e2ea2f1fc145a56dff998bc8215525b0a1e Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 28 Feb 2024 00:04:17 +0100 Subject: rtc: ds1511: drop useless computation All the callers of ds1511_rtc_set_time will use the same epoch for tm_year which is defined as the number of years minus 1900 since POSIX.1-2001.
