Subject: [PATCH] correct disabling of -Wshift-negative-value
Date: Mon, 14 Apr 2025 16:23:36 +0200 [thread overview]
Message-ID: <10b1ebd8-5d32-41a2-9454-1b40e98d5187@suse.com> (raw)
The warning is supported only from gcc6 onwards, hence its disabling
needs probing that the (positive) option is actually supported.
Fixes: 1344794a59db ("Kbuild: add -Wno-shift-negative-value where -Wextra is used")
