Subject: [PATCH v8 5/8] PM / EM: remove em_register_perf_domain
Date: Wed, 27 May 2020 10:58:51 +0100	[thread overview]
Message-ID: <20200527095854.21714-6-lukasz.luba@arm.com> (raw)
In-Reply-To: <20200527095854.21714-1-lukasz.luba@arm.com>

Remove old function em_register_perf_domain which is no longer needed.
There is em_dev_register_perf_domain that covers old use cases and new as
well.
