From c10cdf218a19864764a511859205e3488bc063d1 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Fri, 31 May 2013 11:37:23 -0300 Subject: [PATCH] [media] exynos4-is: Remove WARN_ON() from __fimc_pipeline_close() It's not a critical error to call __fimc_pipeline_close() with missing sensor subdev entity. Replace WARN_ON() with pr_warn() and return 0 instead of -EINVAL to fix control flow in some conditions.
