Subject: [PATCH 3/4] clocksource: csky: Using CPUHP_AP_ONLINE_DYN
Date:   Mon,  1 Mar 2021 14:28:21 +0000
Message-Id: <1614608902-85038-3-git-send-email-guoren@kernel.org>

From: Guo Ren <guoren@linux.alibaba.com>

Remove C-SKY clocksource custom definitions in hotplug.h:
 - CPUHP_AP_CSKY_TIMER_STARTING

For coding convention.
