Subject[PATCH v4 0/1] HID: Report Descriptor in Sysfs
This is version 4 of the patch, with Documentation as requested by Greg KH,
a version number fixed in the documentation, and sent to the right people
this time. (Sorry for the noise; I forgot to re-run after
I added the docs for v3).

Original email follows:

So I'd like to have access to the HID report descriptor in a sysfs entry, so
I can read it without opening the device. hid-core seemed like the place to
put it.

Using the /sys/class links, for hidraw devices, this puts a new file,
report_descriptor in the directory:

For my USB device (for example), the new file is in:

For my Bluetooth device, the new file is in:

I'm not super confident that these file locations are the best place, but I
made a best guess so that it could be discussed. The current location is
where the hid-core stuff lives. Is there a reason these directories are
named bus:vendor:product:id (instead of hid-core or something similar)? Is
there a better way to do this?
