Subject: [PATCH v4 07/27] bus: mhi: host: Rename "struct mhi_tre" to "struct mhi_ring_element"
Date: Mon, 28 Feb 2022 18:13:24 +0530 [thread overview]
Message-ID: <20220228124344.77359-8-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20220228124344.77359-1-manivannan.sadhasivam@linaro.org>
Structure "struct mhi_tre" is representing a generic MHI ring element and
not specifically a Transfer Ring Element (TRE). Fix the naming.
