Joshua Clayton 0af10eed9b HID: core: fix dmesg flooding if report field larger than 32bit
Only warn once of oversize hid report value field

On HP spectre x360 convertible the message:
hid-sensor-hub 001F:8087:0AC2.0002: hid_field_extract() called with n (192) > 32! (kworker/1:2)
is continually printed many times per second, crowding out all else.
Protect dmesg by printing the warning only one time.

The size of the hid report field data structure should probably be increased.
The data structure is treated as a u32 in Linux, but an unlimited number
of bits in the USB hid spec, so there is some rearchitecture needed now that
devices are sending more than 32 bits.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
