All driver sources are upstream Linux kernel code enhanced with Quectel device IDs backported from kernel 6.12.
drivers/usb/serial/option.c ← enhanced with all Quectel USB serial IDs
drivers/usb/serial/usb_wwan.c ← upstream (no Quectel-specific changes)
drivers/usb/serial/usb-wwan.h ← upstream header
drivers/net/usb/qmi_wwan.c ← enhanced with all Quectel QMI IDs
patches/option.c.patch ← diff: vanilla → enhanced (for in-kernel)
patches/qmi_wwan.c.patch ← diff: vanilla → enhanced (for in-kernel)
Makefile ← out-of-tree module build
make && sudo make install
