Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (34 commits) HID: roccat: Update sysfs attribute doc HID: roccat: don't use #pragma pack HID: roccat: Add support for Roccat Kone[+] v2 HID: roccat: reduce number of functions in kone and pyra drivers HID: roccat: declare meaning of pack pragma usage in driver headers HID: roccat: use class for char device for sysfs attribute creation sysfs: Introducing binary attributes for struct class HID: hidraw: add compatibility ioctl() for 32-bit applications. HID: hid-picolcd: Fix memory leak in picolcd_debug_out_report() HID: picolcd: fix misuse of logical operation in place of bitop HID: usbhid: base runtime PM on modern API HID: replace offsets values with their corresponding BTN_* defines HID: hid-mosart: support suspend/resume HID: hid-mosart: ignore buttons report HID: hid-picolcd: don't use flush_scheduled_work() HID: simplify an index check in hid_lookup_collection HID: Hoist assigns from ifs HID: Remove superfluous __inline__ HID: Use vzalloc for vmalloc/memset(,0...) HID: Add and use hid_<level>: dev_<level> equivalents ...
