Subject: [PATCH] media: mali-c55: add padding to mali_c55_params_ccm structure
Date: Tue, 15 Sep 2026 22:24:48 +0200 [thread overview]
Message-ID: <20260915202458.3673504-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The newly added structure has extra padding on the on
some architectures, which triggers a pedantic uapi check:
./usr/include/linux/media/arm/mali-c55-config.h:807:1: error: padding struct size to alignment boundary with 2 bytes [-Werror=padded]
Add explicit padding here to avoid risking information leaks
and incompatibilities between architectures.
Fixes: bb401df68c06 ("media: mali-c55: Add support for CCM")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
