Public bug reported:
[Impact]
Backported to bionic/linux commit f83baa0cb6cf ("HID: add hid_is_usb() function
to make it simpler for USB detection") brings to HID_ASUS usage of hid_is_usb()
which is provided by USB_HID. If HID_ASUS is built as module but USB_HID is
not, the kernel build will fail (like linux-azure) did:
ERROR: "usb_hid_driver" [drivers/hid/hid-asus.ko] undefined!
[Fix]
Because of backport of commit commit f83baa0cb6cf ("HID: add
hid_is_usb() function to make it simpler for USB detection"), the
bionic/linux needs also backport of commit c4f0126d487f ("HID: asus: Add
depends on USB_HID to HID_ASUS Kconfig option").
[Test Plan]
Build HID_ASUS as module with or without USB_HID.
[Where problems could occur]
It's a new KConfig dependency, so configs using HID_ASUS without USB_HID
will loose HID_ASUS. This is expected, so no problems should occur.
