[PATCH v2 11/14] USB: serial: keyspan_pda: clean up xircom/entrega support

Johan Hovold johan at kernel.org
Tue Oct 27 05:25:02 EDT 2020


Drop the separate Kconfig symbol for Xircom / Entrega and always include
support in the keyspan_pda driver.

Note that all configs that enabled CONFIG_USB_SERIAL_XIRCOM also enable
CONFIG_USB_SERIAL_KEYSPAN_PDA.

 - update the defconfigs (Sebastian)
