[PATCH v1 1/1] platform/x86: asus-wmi: fix TUF laptop RGB variant

[Luke D. Jones]

In kbd_rgb_mode_store the dev_get_drvdata() call was assuming the device
data was asus_wmi when it was actually led_classdev.

This patch corrects this by making the correct chain of calls to get the
asus_wmi driver data.
