Subject: kernel: usb: package MaxLinear/Exar USB serial driver
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d39d626b23756fe574ad46e093f5a796b1861b17;p=thirdparty%2Fopenwrt.git

kernel: usb: package MaxLinear/Exar USB serial driver

Currently, MaxLinear/Exar USB serial devices are supported via out-of-tree
usb-serial-xr_usb_serial_common driver which is broken on 6.12.

So since upstream has support for these devices since 6.5 lets package
the in-tree driver to be able to drop the out-of-tree one.
