Subject: [PATCH] clocksource: Remove unused dw_apb_clockevent functions
From: "Dr. David Alan Gilbert" <linux@...blig.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@...blig.org>
