Subject: [PATCH v2 01/18] media: allegro: nal-hevc: Refactor nal_hevc_sub_layer_hrd_parameters
Date: Tue, 07 May 2024 16:27:06 +0000 [thread overview]
Message-ID: <20240507-cocci-flexarray-v2-1-7aea262cf065@chromium.org> (raw)
In-Reply-To: <20240507-cocci-flexarray-v2-0-7aea262cf065@chromium.org>
Replace all the single elements arrays with the element itself.
Pahole shows the same padding and alignment for x86 and arm in both
situations.
This fixes this cocci warning:
drivers/media/platform/allegro-dvt/nal-hevc.h:102:14-22: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
