[PATCH 0/1] apple-gmux: Assign apple_gmux_data before registering

[Lukas Wunner <lukas@wunner.de>]

Hi Darren,

the following patch is a useful fix for apple-gmux by Matthew Garrett
which is well over a year old but unfortunately never got merged.

The commit message makes it sound as if the fix is only needed for
reprobing (in case apple-gmux registers after the DRM drivers).
I'm not yet sure if we'll use reprobing or deferred initialization,
however the patch is needed even if we go with deferred initialization
as it fixes a race condition that is triggered by invoking a handler
callback between the call to vga_switcheroo_register_handler() and the
assignment of apple_gmux_data.

The patch has seen extensive testing and is actively used by myself
and others on various MacBook Pro models.

Could you take a look at the patch and (barring any objections) ack it?

Thanks,

Lukas
