Hi Jiri, After merging the hid tree, today's linux-next build (x86_64 allmodconfig) failed like this: samples/hidraw/hid-example.c: In function 'main': samples/hidraw/hid-example.c:103: warning: implicit declaration of function 'HIDIOCSFEATURE' samples/hidraw/hid-example.c:111: warning: implicit declaration of function 'HIDIOCGFEATURE' tmp/ccK96SHd.o: In function `main': hid-example.c:(.text+0x205): undefined reference to `HIDIOCSFEATURE' hid-example.c:(.text+0x23e): undefined reference to `HIDIOCGFEATURE' Caused by commit c54ea4918c2b ("HID: Documentation for hidraw"). I can only assume that linux/hidraw.h is being included from /usr/include and not the kernel tree being built? I have used the hid tree from next-20110406 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
