From 6f482c4729d9040945f6d1e7ca1171eba9b5a5d6 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Wed, 19 Apr 2023 09:07:09 +0200 Subject: [PATCH] media: imx: imx7-media-csi: Get rid of superfluous call to imx7_csi_mbus_fmt_to_pix_fmt There is no need to convert input pixformat to mbus_framefmt and back again. Instead apply pixformat width constrains directly. Assign compose values before adjusting pixformat height/width.
