From 84f5f31f110e5e8cd5581e8efdbf8c369e962eb9 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Tue, 1 Mar 2022 21:33:06 +0530 Subject: [PATCH] bus: mhi: host: Rename "struct mhi_tre" to "struct mhi_ring_element" Structure "struct mhi_tre" is representing a generic MHI ring element and not specifically a Transfer Ring Element (TRE). Fix the naming.
