Mark it as __initconst so its memory can be released afterwards --
roughly 5.7 kB. In turn, the callback function can be marked with

Also the touchpad_led_init() function can be marked __init as it's only
referenced from dell_init() -- an __init function.

This patch removes the null test on block. block is initialized at the
beginning of the function to &wblock->gblock. Since wblock is
dereferenced prior to the null test, wblock must be a valid pointer,
and &wblock->gblock cannot be null.

When bl_power support got added to asus-wmi, the error handling for it was
written to ignore -ENODEV, to avoid not registering a backlight interface for
models which have no bl_power control, but do have brightness control.

At the same time the error handling for brightness_max was modified to do the
same, this is wrong, when there is no brightness_max asus-wmi should not
register a backlight interface.

Note the caller of asus_wmi_backlight_init already special cases -ENODEV,
and will not cause the wmi driver regristration to fail because of a
-ENODEV return from asus_wmi_backlight_init.

It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036
https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.

And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).

So this patch does 3 things to get proper rfkill handling on these models:

1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.

2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1

3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.
