6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
[ Upstream commit e53c741303a59ee1682e11f61b7772863e02526d ]
The "ring" variable has an upper bounds check but nothing checks for
negatives. This code uses kstrtouint() already and it was obviously
intended to be declared as unsigned int. Make it so.
Fixes: dbc8876dd873 ("crypto: qat - add rp2svc sysfs attribute")
