dma_heap_allocation_data defines the UAPI as follows:
struct dma_heap_allocation_data { __u64 len; __u32 fd; __u32 fd_flags; __u64 heap_flags; };
However, dma_heap_buffer_alloc() casts both fd_flags and heap_flags into unsigned int. We're inconsistent with types in the non UAPI arguments. This patch fixes it.
Thank you for your patch; I've pushed it to drm-misc-next.
Best, Sumit.
