Simon Glass 20740e4fbc dm: core: Fix allocation of empty of-platdata ... With of-platdata we always have a dtv struct that holds the platform data provided by the driver_info record. However, this struct can be empty if there are no actual devicetree properties provided. The upshot of empty platform data is that it will end up as a zero-size member in the BSS section, which is fine. But if the driver specifies plat_auto then it expects the correct amount of space to be allocated. At present this does not happen, since device_bind() assumes that the platform-data size will always be >0. As a result we end up not allocating the space and just use the BSS region, overwriting whatever other contents are present. Fix this by removing the condition that platform data be non-empty, always allocating space if requested. This fixes a strange bug that has been lurking since of-platdata was implemented. It has likely never been noticed since devices normally have at least some devicetree properties, BSS is seldom used on SPL, the dtv structs are normally at the end of bss and the overwriting only happens if a driver changes its platform data. It was discovered using sandbox_spl, which exercises more features than a normal board might, and the critical global_data variable 'gd' happened to be at the end of BSS.
