File curl-CVE-2023-28322.patch of Package curl.30927
From 7815647d6582c0a4900be2e1de6c5e61272c496b Mon Sep 17 00:00:00 2001
From: Daniel Stenberg <daniel@haxx.se>
Date: Tue, 25 Apr 2023 08:28:01 +0200
Subject: [PATCH] lib: unify the upload/method handling
By making sure we set state.upload based on the set.method value and not
independently as set.upload, we reduce confusion and mixup risks, both
internally and externally.
Closes #11017
