So, any ioctl send to the interface are reflected at the entities managed by the interface. However, when a device is used, other interfaces for the same hardware could be decoupled from the entities linked to them, because the hardware may have some parts busy. That's for example, what happens when an hybrid TV device is in use. If it is streaming analog TV or capturing signals from S-Video/Composite connectors, typically the digital part of the hardware can't be used and vice-versa. This is generally due to some internal hardware or firmware limitation, that it is not easily mapped via data pipelines. What the Kernel drivers do internally is that they decouple the hardware from the interface. So, all changes, if allowed, are done only at some interface cache, but not physically changed at the hardware. The usage is similar to the usage of the MEDIA_LNK_FL_ENABLED on data links. So, let's use the same flag to indicate if either the interface to entity link is bound/enabled or not.

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.
