It should be "it, as pointed out by Lukas Wunner", sorry for the mistake… :-/

[Nouveau] [PATCH v2 2/2] nouveau/bl: Do not register interface if Apple GMUX detected

[Pierre Moreau]

Nouveau to register its own backlight interface.

v2: Do not split information message on two lines as it prevents from grepping
it, as pointed out by Hans de Goede
