From cb3e85fe19575cce8af82bc62a070c72e8f781b8 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Sat, 9 Apr 2011 01:43:18 +0200 Subject: HID: hidraw: fix samples miscompilation On systems where userspace doesn't have new hidraw.h populated to /usr/include, the hidraw sample won't compile as it's missing the new ioctl defitions. Introduce temporary ugly workaround to define the ioctls "manually" in such cases, just to avoid miscompilation in allmodconfig cases.
