From f57cdbd34cb435ed3b7d38be6276f7f389e8d0e9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 25 Jul 2017 11:39:14 -0400 Subject: [PATCH] media: v4l: use WARN_ON(1) instead of __WARN() __WARN() cannot be used in portable code, since it is only available on some architectures and configurations: drivers/media/platform/pxa_camera.c: In function 'pxa_mbus_config_compatible': drivers/media/platform/pxa_camera.c:642:3: error: implicit declaration of function '__WARN'; did you mean '__WALL'? [-Werror=implicit-function-declaration] The common way to express an unconditional warning is WARN_ON(1), so let's use that here.
