Subject: [PATCH 2/8] cpufreq: remove unicore32 driver
Date: Tue, 23 Jun 2020 09:57:38 +0300 [thread overview]
Message-ID: <20200623065744.18393-3-rppt@kernel.org> (raw)
In-Reply-To: <20200623065744.18393-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
The unicore32 port is removed from the kernel.
There is no point to keep stale cpufreq driver for this architecture.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
