From 4dfec0d1d7b9970f36931de714b379dbeaed83f8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 26 Oct 2020 20:39:55 +0100 Subject: [PATCH] matroxfb: avoid -Warray-bounds warning The open-coded list_for_each_entry() causes a harmless warning: drivers/video/fbdev/matrox/matroxfb_base.c: In function 'matroxfb_register_driver': include/linux/kernel.h:856:3: warning: array subscript -98 is outside array bounds of 'struct list_head[1]' [-Warray-bounds] Use the normal list_for_each_entry instead.
