From 9fcf2b3c1c0276650fea537c71b513d27d929b05 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Sun, 17 Jun 2018 10:48:22 +0200 Subject: [PATCH] drm/atmel-hlcdc: check stride values in the first plane The statement always evaluates to true since the struct fields are arrays. This has shown up as a warning when compiling with clang: warning: address of array 'desc->layout.xstride' will always evaluate to 'true' [-Wpointer-bool-conversion] Check for values in the first plane instead.
