[PATCH 3/9] mt76: usb: introduce __mt76u_init utility routine

[Lorenzo Bianconi]

Introduce __mt76u_init unitility routine and move mt7615 usb bus ops
into mt7615 module in order to allow specifying driver specific
parameter.
This is a preliminary patch to add usb support to mt7921 driver.

[PATCH 3/9] mt76: usb: introduce __mt76u_init utility routine

[Lorenzo Bianconi]

Introduce __mt76u_init unitility routine and move mt7615 usb bus ops
into mt7615 module in order to allow specifying driver specific
parameter.
This is a preliminary patch to add usb support to mt7921 driver.
