From: Takashi Sakamoto Date: Thu, 1 Jun 2023 14:49:37 +0000 (+0900) Subject: firewire: fix warnings to generate UAPI documentation X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0258d889a7ee28310dbe3f5d4d039b48a1d080ad;p=linux.git firewire: fix warnings to generate UAPI documentation Any target to generate UAPI documentation reports warnings to missing annotation for padding member in structures added recently. This commit suppresses the warnings.
