[PATCH] video: backlight: remove unused header

[Paul Bolle <pebolle@tiscali.nl>]

Commit 9befe40f6e018e508b047eb76d189ede9b4ff03d ("video: backlight:
support s6e8ax0 panel driver based on MIPI DSI") added s6e8ax0.h, but
no file includes it. That's probably a good thing, because it declares
an extern void function that is defined static int in s6e8ax0.c.
Besides, that function is also wrapped in the module_init() macro, which
should do everything needed to make that function available to the code
outside of s6e8ax0.c. This header can safely be removed.

0) Tested mainly by using various git tools on the (history of the)
tree.

1) Shouldn't s6e8ax0_init() and s6e8ax0_exit(), both in s6e8ax0.c, carry
the usual __init and __exit attributes?

2) But note that all the module related code in s6e8ax0.c seems moot
currently: EXYNOS_LCD_S6E8AX0 is a boolean Kconfig symbol, so the code
can only be used builtin. So, as far as I can tell, either that symbol
(and the symbols on which it depends) should be made tristate, or the
module related code can be removed from s6e8ax0.c.
