[PATCH] HID: core: demote warning to debug level

[Ben Hutchings <benh@debian.org>]

[-- Attachment #1: Type: text/plain, Size: 1748 bytes --]

From: Matteo Croce <teknoraver@meta.com>

The log level for short  messages was changed from debug to warning,
flooding syslog on systems with devices that regularly send
short reports, in my case an UPS:

    $ dmesg |grep -c 'Event data for report .* was too short'
    35

Demote it back to debug level.

Fixes: 0a3fe972a7cb ("HID: core: Mitigate potential OOB by removing bogus memset()")
Signed-off-by: Matteo Croce <teknoraver@meta.com>
[bwh: Re-sending this fix which was applied and then lost in a mis-
 merge.  Add a second Fixes trailer so this should reach all stable
 branches that have the warning.]

and applied to the hid tree as commit d0ff08d946c8, but then it was
lost in merge commit aa776949fb77 "Merge branch 'for-7.2/wiimote' into
for-linus".
