4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Agner <stefan@xxxxxxxx>
commit 9fcf2b3c1c0276650fea537c71b513d27d929b05 upstream.
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.
Fixes: 1a396789f65a ("drm: add Atmel HLCDC Display Controller support")
