From 92adf64d3ae643bd51a38a2bbc87a73bd8479528 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Mon, 20 Mar 2023 13:06:32 +0000 Subject: [PATCH] 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).
