Subject: [PATCH v2 15/18] firmware: qcom_scm-32: Add device argument to atomic calls
Date: Tue, 12 Nov 2019 13:22:51 -0800	[thread overview]
Message-ID: <1573593774-12539-16-git-send-email-eberman@codeaurora.org> (raw)
In-Reply-To: <1573593774-12539-1-git-send-email-eberman@codeaurora.org>

Add this unused parameter to reduce merge friction between SMCCC and
legacy based conventions.
