Subject: [PATCH 5.17 0202/1126] crypto: qat - fix a signedness bug in get_service_enabled()

From: Dan Carpenter <dan.carpenter@...cle.com>

[ Upstream commit 844318dfd31f7c99f6cebbdba5d6f8392c4c115c ]

The "ret" variable needs to be signed or there is an error message which
will not be printed correctly.

Fixes: 0cec19c761e5 ("crypto: qat - add support for compression for 4xxx")
