Subject: [PATCH 1/3] efi/memattr: Convert efi_memattr_init() return type to void
Date: Mon, 06 Jan 2025 11:02:50 -0800 [thread overview]
Message-ID: <20250106-efi_fw_bug-v1-1-01a8eb40bfeb@debian.org> (raw)
In-Reply-To: <20250106-efi_fw_bug-v1-0-01a8eb40bfeb@debian.org>
The efi_memattr_init() function's return values (0 and -ENOMEM) are never
checked by callers. Convert the function to return void since the return
status is unused.
