Subject: [PATCH v2 3/6] kbuild: rust: move `-Dwarnings` handling to `Makefile.extrawarn`
Date: Thu, 14 Aug 2025 12:14:43 +0200 [thread overview]
Message-ID: <20250814-kbuild-werror-v2-3-c01e596309d2@linutronix.de> (raw)
In-Reply-To: <20250814-kbuild-werror-v2-0-c01e596309d2@linutronix.de>
From: Miguel Ojeda <ojeda@kernel.org>
Following commit e88ca24319e4 ("kbuild: consolidate warning flags
in scripts/Makefile.extrawarn"), move `-Dwarnings` handling into
`Makefile.extrawarn` like C's `-Werror`.
No functional change intended.
