Subject: [PATCH 6.7 110/713] rtc: test: Fix invalid format specifier.

From: David Gow <davidgow@...gle.com>

[ Upstream commit 8a904a3caa88118744062e872ae90f37748a8fd8 ]

'days' is a s64 (from div_s64), and so should use a %lld specifier.

This was found by extending KUnit's assertion macros to use gcc's
__printf attribute.

Fixes: 1d1bb12a8b18 ("rtc: Improve performance of rtc_time64_to_tm(). Add tests.")
