Subject: [PATCH 1/5] firmware: arm_scmi: always initialize protocols
Date: Thu,  8 Oct 2020 16:37:18 +0200	[thread overview]
Message-ID: <20201008143722.21888-1-etienne.carriere@linaro.org> (raw)

Remove the IDR replacement that prevent initializing an SCMI protocol
when it has already been initialized. This is needed when there are
several SCMI agents that do implement a given SCMI protocol unless
what only the related SCMI protocol communication is initialized only
for first probed agent.
