In ca8210_probe the allocated pdata needs to be assigned to
spi_device->dev.platform_data before calling ca8210_get_platform_data. 
Othrwise when ca8210_get_platform_data fails pdata cannot be released.

Could you review this patch for the ca8210 driver?

As Harry seems to be unavailable I am taking this patch directly.


This patch has been applied to the wpan tree and will be
part of the next pull request to net. Thanks!
