Subject: [PATCH v3 02/18] media: xilinx: Refactor struct xvip_dma
Date: Mon, 27 May 2024 21:08:52 +0000	[thread overview]
Message-ID: <20240527-cocci-flexarray-v3-2-cda09c535816@chromium.org> (raw)
In-Reply-To: <20240527-cocci-flexarray-v3-0-cda09c535816@chromium.org>

Replace a single element array with a single field.

The following cocci warning is fixed:
drivers/media/platform/xilinx/xilinx-dma.h:100:19-22: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
