Subject: [PATCH] clocksource: Remove unused dw_apb_clockevent functions
Date: Fri, 25 Oct 2024 21:31:01 +0100	[thread overview]
Message-ID: <20241025203101.241709-1-linux@treblig.org> (raw)

From: "Dr. David Alan Gilbert" <linux@treblig.org>

dw_apb_clockevent_pause(), dw_apb_clockevent_resume() and
dw_apb_clockevent_stop() have been unused since 2021's
commit 1b79fc4f2bfd ("x86/apb_timer: Remove driver for deprecated
platform")

Remove them.

(Some of the other clockevent functions are still called by
dw_apb_timer_of.c  so I guess it is still in use?)

Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org>
