From b72f14ee7eb3e9e2f8a9c4cb807a1ec749a4c022 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 21 Apr 2020 15:57:39 +0200 Subject: [PATCH] media: pci: Fill v4l2_fmtdesc with designated initializers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace initialization of static const v4l2_fmtdesc instances that specify every struct member with designated initializers. This allows not zeroing the reserved fields explicitly, and will avoid a need to patch these drivers every time a reserved field is repurposed.
