Subject: [PATCH 08/10] ath11k: set register access length for MHI driver
Date: Fri, 25 Jun 2021 18:03:53 +0530	[thread overview]
Message-ID: <20210625123355.11578-9-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20210625123355.11578-1-manivannan.sadhasivam@linaro.org>

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.
