openwrt/target/linux/generic/patches-4.4/021-bcma-from-4.6.patch
Stijn Tintel 8072264b96 kernel: update kernel 4.4 to version 4.4.19 
Refresh patches for all targets that support kernel 4.4.
Compile-tested on all targets that use kernel 4.4 and aren't marked broken.
Runtime-tested on ar71xx, octeon and x86/64.
