Hi Jiri, After merging the hid tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: drivers/hid/hid-input.c: In function 'hidinput_hid_event': drivers/hid/hid-input.c:865:6: error: 'struct hid_device' has no member named 'battery_val' drivers/hid/hid-input.c:866:3: error: 'struct hid_device' has no member named 'battery_min' drivers/hid/hid-input.c:866:3: error: 'struct hid_device' has no member named 'battery_max' Caused by commit 4f5ca836bef3 ("HID: hid-input: add support for HID devices reporting Battery Strength"). Those members are only defined when CONFIG_HID_BATTERY_STRENGTH is set. I have used the hid tree from next-20111128 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
