[PATCH] [media] exynos-gsc: Avoid spamming the log on VIDIOC_TRY_FMT

From: Javier Martinez Canillas
Date: Tue Jan 24 2017 - 16:42:47 EST


There isn't an ioctl to enum the supported field orders, so a user-space
application can call VIDIOC_TRY_FMT using different field orders to know
if one is supported. For example, GStreamer does this so during playback
dozens of the following messages appear in the kernel log buffer:

[ 442.143393] Not supported field order(4)

Instead of printing this as an error, just keep it as debug information.
