Subject: [PATCH v4 4/6] ath11k: set register access length for MHI driver
Date: Thu,  6 May 2021 12:32:23 -0700	[thread overview]
Message-ID: <1620329545-32328-5-git-send-email-bbhatt@qti.qualcomm.com> (raw)
In-Reply-To: <1620329545-32328-1-git-send-email-bbhatt@qti.qualcomm.com>

From: Bhaumik Bhatt <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.
