X-Git-Url: http://git.99rst.org/?a=commitdiff_plain;h=2a31359c478025850a9feeb684b758ede62bf9c4;p=openwrt-packages.git

modemmanager: add support for wwan subsystem in hotplug

WWAN devices may now be exposed in the new 'wwan' subsystem in the
kernel (since 5.13), initially applicable to devices exposed in PCIe
(no USB), but at some point may also apply to USB devices that until
now were exposed via other subsystems (e.g. usbmisc, tty).
