[Openvpn-devel] [XS] Change in openvpn[master]: Fix warnings about conversion from int to unsigned char/uint8_t

[cron2 (C. Review) <ge...@op...>]

cron2 has submitted this change. ( http://gerrit.openvpn.net/c/openvpn/+/1328?usp=email )

Change subject: Fix warnings about conversion from int to unsigned char/uint8_t
......................................................................

Fix warnings about conversion from int to unsigned char/uint8_t

When compiling with cmake -DCMAKE_BUILD_TYPE=ASAN under Ubuntu 25.10
(gcc 15.2.0).

Explicitly cast these instances to uint8_t/unssigned char to silence this
warning.
