Subject: [PATCH v3 4/6] ath11k: set register access length for MHI driver
Date: Wed, 5 May 2021 10:08:19 -0700 [thread overview]
Message-ID: <1620234501-30461-5-git-send-email-bbhatt@codeaurora.org> (raw)
In-Reply-To: <1620234501-30461-1-git-send-email-bbhatt@codeaurora.org>
MHI driver requires register space length to add range checks and
prevent memory region accesses outside of that for MMIO space.
Set it before registering the MHI controller.
