X-Git-Tag: v6.1.21~316
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4cd8ffa4880045ee829851dff1fba5fd2fae1524;p=platform%2Fkernel%2Flinux-starfive.git

HID: uhid: Over-ride the default maximum data buffer value with our own

commit 1c5d4221240a233df2440fe75c881465cdf8da07 upstream.

The default maximum data buffer size for this interface is UHID_DATA_MAX
(4k).  When data buffers are being processed, ensure this value is used
when ensuring the sanity, rather than a value between the user provided
value and HID_MAX_BUFFER_SIZE (16k).
