| |
The first patch in this series changed the platform_device_alloc function to assign the u64 .dma_mask pointer of struct device to the address of a u64 .dma_mask member of struct platform_object.
This means that we no longer should allocate memory for the .dma_mask pointer of struct device when using platform_device_alloc() and the u64 .dma_mask of struct platform_object that it points to will be freed when the release callback function platform_device_release is called.
