Subject: [PATCH v3 1/5] remoteproc: fix the wrong default value of is_iomem
Date: Thu,  5 Aug 2021 11:32:02 +0800	[thread overview]
Message-ID: <20210805033206.1295269-1-aisheng.dong@nxp.com> (raw)

Currently the is_iomem is a random value in the stack which may
be default to true even on those platforms that not use iomem to
store firmware.
