Except for the build error, I see no other issues on the GATT part of
these patches. Someone else needs to review/comment on the part
touching src/device.c though (maybe Johan himself?)

This patch introduces a build failure:
deviceinfo/deviceinfo.c: In function ?configure_deviceinfo_cb?:
deviceinfo/deviceinfo.c:108:19: error: variable ?end? set but not used
[-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors
Please make sure every patch on the series is buildable (when applied
on order). In this case, you should introduce the variable only on the
commit where it is used.

Read the PNP ID characteristic of the DeviceInfo Service, and
store it inside the btd_device, for use by other profiles.
