Fixes:
http://autobuild.buildroot.net/results/23f0f7386f7d430c402b24f3b58b1c20c1c8344a/

Linux commit d69d8048459 "driver core: have match() callback in struct
bus_type take a const *", which was added in 6.11-rc1, changed the interface
for sysfs match callback to accept a const struct device_driver, breaking
the build of dahdi-linux:

 CC [M]  build/dahdi-linux-3.3.0/drivers/dahdi/dahdi-sysfs.o
build/dahdi-linux-3.3.0/drivers/dahdi/dahdi-sysfs.c:275:27: error: initialization
   of "int (*)(struct device *, const struct device_driver *)" from incompatible
   pointer type "int (*)(struct device *, struct device_driver *)"
   [-Werror=incompatible-pointer-types]
  275 |         .match          = span_match,

Add a patch submitted upstream to fix that.
