[PATCH 3/3] ARM: imx: don't allocate memory for .dma_mask of struct device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
