Hello,
mfd_add_device() (defined in drivers/mfd/mfd-core.c) is a wrapper do allocate platform_devices.
It contains:
ret = platform_device_add_data(pdev, cell->platform_data, cell->data_size);
If cell->data_size is 0 (and so likely cell->platform_data == NULL), still pdev->dev.platform_data get assigned ZERO_SIZE_PTR.
IMHO the result should better be that pdev->dev.platform_data ends being NULL, too. Agreed?
If yes, where is the right place to fix that, mfd_add_device() or platform_device_add_data()?
Best regards Uwe
