2013-03-27HID: hidraw: warn if userspace headers are outdatedJiri Kosina1-2/+1
Put a warning into sample hidraw code in samples/hidraw/hid-example.c in case the userspace headers are missing the necessary defines and need to be updated. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-04-21HID: hid-example: fix some build issuesRandy Dunlap1-0/+2
samples/hid-example.o needs some Kconfig and Makefile additions in order to build. It should use <linux/*.h> headers from the build tree, so use HEADERS_CHECK to require that those header files be present. Change the kconfig symbol from tristate to bool since userspace cannot be built as loadable modules. However, I don't understand why the userspace header files are not present as reported in Andrew's build log, since it builds OK on x86_64 without any of these changes.

2011-04-08HID: hidraw: fix samples miscompilationJiri Kosina1-0/+11
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.
