#1249145 — [PATCH] [media] horus3a: fix horus3a_attach inline wrapper

The 'static inline' version of horus3a_attach() is incorrectly
copied from another file, which results in a build error when
CONFIG_DVB_HORUS3A is disabled:

In file included from /git/arm-soc/drivers/media/pci/netup_unidvb/netup_unidvb_core.c:34:0:

This changes the code to have the correct prototype.

I posted the same patch a couple of weeks ago and was already picked
by Mauro on his fixes branch [0].

AFAIU that branch contains 4.3-rc material so I guess it will land
into mainline soon.

[0]: http://git.linuxtv.org/cgit.cgi/media_tree.git/commit/?h=fixes&id=de5abc98bf34e06d7accd943c4057843db921f00

Best regards,
Javier
