[PATCH] v4l2-compat-ioctl32: replace pr_warn by pr_debug

Every time compat32 encounters an unknown ioctl it will call pr_warn. However, that's very irritating since it is perfectly normal that this happens. For example, applications often try to call an ioctl to see if it exists, and if that's used with an older kernel where compat32 doesn't support

[PATCH 0/2] MC minor cleanups

This two patch series do some minor cleanups as suggested by Sakari. Mauro Carvalho Chehab (2): [media] media_entity: remove gfp_flags argument [media] media-device: use unsigned ints on some places drivers/media/dvb-core/dvbdev.c| 3 +-- drivers/media/media-device.c | 7 ---

[PATCH 2/2] [media] media-device: use unsigned ints on some places

The entity->num_pads are defined as u16. So, better to use an unsigned int, as this prevents additional warnings when W=2 (or W=1 on some architectures). The "i" counter at __media_device_get_topology() is also a monotonic counter that should never be below zero. So, make it unsigned too.

[PATCH 1/2] [media] media_entity: remove gfp_flags argument

We should not be creating device nodes at IRQ contexts. So, the only flags we'll be using will be GFP_KERNEL. Let's remove the gfp_flags, in order to make the interface simpler. If we ever need it, it would be easy to revert those changes. While here, remove an extra blank line. Suggested-by:

[PATCH] rc: gpio-ir-recv: allow flush space on idle

Many decoders require a trailing space (period without IR illumination) to be delivered before completing a decode. Since the gpio-ir-recv driver only delivers events on gpio transitions, a single IR symbol (caused by a quick touch on an IR remote) will not be properly decoded without the use of
