Subject: [PATCH 07/17] firmware: qcom_scm-64: Remove qcom_scm_call_do_smccc
Date:   Mon,  4 Nov 2019 17:27:26 -0800
Message-Id: <1572917256-24205-8-git-send-email-eberman@codeaurora.org>
In-Reply-To: <1572917256-24205-1-git-send-email-eberman@codeaurora.org>
References: <1572917256-24205-1-git-send-email-eberman@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Remove thin wrapper to qcom_scm_call_do_smccc because it doesn't do
enough of anything interesting to dedicate its own function.
