Subject: [PATCH v2 2/2] HID: uhid: Over-ride the default maximum data buffer value with our own
Date: Mon, 23 Jan 2023 12:39:12 +0000 [thread overview]
Message-ID: <20230123123912.360651-2-lee@kernel.org> (raw)
In-Reply-To: <20230123123912.360651-1-lee@kernel.org>
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).
