Subject: [PATCH v1 4/6] ath11k: set register access length for MHI driver
Date: Fri, 16 Apr 2021 11:47:03 -0700	[thread overview]
Message-ID: <1618598825-18629-5-git-send-email-bbhatt@codeaurora.org> (raw)
In-Reply-To: <1618598825-18629-1-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.
