Subject: media: venus: Refactor struct hfi_uncompressed_format_supported
Author:  Ricardo Ribalda <riba...@chromium.org>
Date:    Wed Aug 14 11:39:24 2024 +0000

plane_info is not a typical array, the data is not contiguous:
pinfo = (void *)pinfo + sizeof(*constr) * num_planes +
        2 * sizeof(u32);

Replace the single element array with a single element field.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_helper.h:1009:36-46: WARNING use 
flexible-array member instead 
(https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
