[PATCH] fbcon: mark dummy functions 'inline'

[PATCH] fbcon: mark dummy functions 'inline'

[Arnd Bergmann]

The newly introduced fb_console_init/exit declarations have a
dummy alternative that is marked 'static' in the header but not
inline, leading to a warning whenever the header gets included:

In file included from drivers/video/fbdev/core/fbmem.c:35:0:
include/linux/fbcon.h:9:13: error: 'fb_console_exit' defined but not used [-Werror=unused-function]

This adds the intended 'inline'.

Fixes: 6104c37094e7 ("fbcon: Make fbcon a built-time depency for fbdev")
