From 490f1ff1e6b20da73438a567fd0f78c14fbebc2e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 10 Mar 2020 17:06:28 +0100 Subject: [PATCH] media: imx: imx7-media-csi: Remove unneeded register read The imx7_csi_dma_reflash() function starts by reading the unrelated register CSI_CSICR18 to then overwrite the read value with a read from register CSI_CSICR3. This is likely due to a bad copy&paste, and is not needed. Remove the extraneous read from register CSI_CSICR18.
