From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxx> In some DT use-cases platform data might be already allocated and passed via AUXDATA. These are the cases where machine level code populates few callbacks in the platform data. This patch adds check and reuses platform_data if its valid, before allocating a new one.
Yes, we had seen this long time ago and IIRC i prepared the patch so Acked-by: Giuseppe Cavallaro <peppe.cavallaro@xxxxxx>
