[PATCH] toshiba_acpi: Fix regression caused by hotkey enabling value

[PATCH] toshiba_acpi: Fix regression caused by hotkey enabling value

[Azael Avalos]

Commit 52cbae0127ad ("toshiba_acpi: Change default Hotkey enabling value")
changed the hotkeys enabling value, as it was the same value Windows uses,
however, it turns out that the value tells the EC that the driver will now
take care of the hardware events like the physical RFKill switch or the
pointing device toggle button.

This patch reverts such commit by changing the default hotkey enabling
value to 0x09, which enables hotkey events only, making the hardware
buttons working again.

Fixes bugs 113331 and 114941.

I wasn't planning on another pull to Linus at r5, but since this is a
regression, I've queued it for 4.6-rc6. It will liketly be the only patch in the
pull request. If Linus objects, we'll push it to 4.7. Either way, I'll tag it
for stable.

Hi Darren,


No problem with me, ohh and thanks, I forgot to include stable.
