From 0642fb4ba68f7158f7a6d92190b3090cf0c7fac6 Mon Sep 17 00:00:00 2001 From: Drew Fustini Date: Tue, 23 Nov 2021 11:25:24 -0800 Subject: [PATCH] clocksource/drivers/pistachio: Fix -Wunused-but-set-variable warning Variable 'overflow' set but not used, but this is the intended behavior. The hardware only updates the counter register after the overflow register read. However, the value of overflow is not actually needed.
