Here is the quote from [1]:
The unit-address must match the first address specified
in the reg property of the node. If the node has no reg property,
the @ and unit-address must be omitted and the node-name alone
differentiates the node from other nodes at the same level

This adds a driver for the Pegasus Notetaker Pen. When connected,
this uses the Pen as an input tablet.
This device was sold in various different brandings, for example
"Pegasus Mobile Notetaker M210",
"Genie e-note The Notetaker",
"Staedtler Digital ballpoint pen 990 01",

Please pull these minor updates for the keys code.
The following changes since commit 7639dad93a5564579987abded4ec05e3db13659d:
Merge tag 'trace-v4.7-2' of

This patch fixes the following (W=1) warnings:
drivers/usb/gadget/udc/mv_u3d_core.c: In function ‘mv_u3d_process_ep_req’:
drivers/usb/gadget/udc/mv_u3d_core.c:124:6: warning: variable ‘trb_complete’
set but not used [-Wunused-but-set-variable]
int trb_complete, actual, remaining_length = 0;
Those are enabled with W=1 make option.
type-limits warnings in uvc_configfs.o and f_hid.c are left because
they are caused by generic macros used in a way where they produce
always-false conditions, e.g.:
CC [M] drivers/usb/gadget/function/uvc_configfs.o
drivers/usb/gadget/function/uvc_config
Fixes all of the unused-but-set-variable warnings enabled when
building with W=1. As described in the first patch, some warnings are
left off. See said patch for more description.

This patch changes the export attributes of the init_user_ns from
GPL-only to any modules. This needed so that non-gpl modules, such as
ZFS, utilize functions like i_(uid|gid)_(read|write).

The musb driver can drop rx packets when heavily loaded. These two
patches address two issues that can cause this. Both issues arose
when an endpoint was reprogrammed. The first patch is a logic bug
that resulted in a shared_fifo in rx mode not having its state

shared_fifo endpoints would only get a previous tx state cleared
out, the rx state was only cleared for non shared_fifo endpoints
Change this so that the rx state is cleared for all endpoints.
This addresses an issue that resulted in rx packets being dropped
silently.
