[PATCH 06/11] HID: asus: introduce small delay on Asus Z13 RGB init

[Antheas Kapenekakis]

The folio keyboard of the Z13 can get stuck in its BIOS mode, where the
touchpad behaves like a mouse and the keyboard start button is not
reliable if we perform the initialization too quickly. This mostly
happens during boot, and can be verified to be caused by hid-asus
through simple blacklisting. A small delay fixes it.
