genode/repos/dde_linux/patches/usb_mem.patch
Sebastian Sumpf d426c5e6c2 dde_linux: make drivers self containing 
Ported drivers list and extract all needed source files. This decouples
ports according to contrib sources and also enables us to revert lxip to
Linux version 3.9, while staying with 3.14 for usb.

Fixes #1285
