Please don't change the sizeof() any structures in your series, because the structure is unallocated changing the size is potentially insidious IMO. data[1] -> data is perfectly fine in this case. --- bod

Replace the old style single element array at the end of the struct with a flex array. The code does not allocate this structure, so the size change should not be a problem. This fixes the following cocci warning: drivers/media/platform/qcom/venus/hfi_helper.h:1233:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays) Signed-off-by: Ricardo Ribalda <ribalda@chromium.org> --- drivers/media/platform/qcom/venus/hfi_helper.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
