Subject: [PATCH v2 06/15] ARM: rpc: use legacy_timer_tick
Date: Fri, 30 Oct 2020 16:17:49 +0100	[thread overview]
Message-ID: <20201030151758.1241164-7-arnd@kernel.org> (raw)
In-Reply-To: <20201030151758.1241164-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

rpc is the only user of the timer_tick() function now, and can
just call the newly added generic version instead.
