Subject: [PATCH 07/17] firmware: qcom_scm-64: Remove qcom_scm_call_do_smccc
Date: Mon,  4 Nov 2019 17:27:26 -0800	[thread overview]
Message-ID: <1572917256-24205-8-git-send-email-eberman@codeaurora.org> (raw)
In-Reply-To: <1572917256-24205-1-git-send-email-eberman@codeaurora.org>

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