Subject: [PATCH v4 4/6] ath11k: set register access length for MHI driver
Date: Thu, 6 May 2021 12:51:43 -0700 [thread overview]
Message-ID: <1620330705-40192-5-git-send-email-bbhatt@codeaurora.org> (raw)
In-Reply-To: <1620330705-40192-1-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.
