[PATCH] asus-wmi: delete impossible condition

[PATCH] asus-wmi: delete impossible condition

[Dan Carpenter]

The "asus->throttle_thermal_policy_mode" variable is a u8 so it can't
be negative.  And we always verify that the value is valid before
setting the policy mode so there is no need to check again here.

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
