platform_device_add_data(pdev, NULL, 0)

[Uwe Kleine-König]

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
