Subject: [PATCH 4/4] loader/efi/linux: Fix Compile Error With Clang
Date: Sat, 25 Oct 2025 10:53:40 -0500 [thread overview]
Message-ID: <20251025155340.578883-5-adhamilt@gmail.com> (raw)
In-Reply-To: <20251025155340.578883-1-adhamilt@gmail.com>
Clang will produce a warning (which is treated as
an error) that "vendor_defined_data" is uninitialized.
This is a "zero length" array member of this struct.
Add conditional compile pragma to allow this to
compile with Clang.
