From 310ec03841a36e3f45fb528f0dfdfe5b9e84b037 Mon Sep 17 00:00:00 2001 From: Barry Song Date: Wed, 5 Jun 2024 13:26:05 +1200 Subject: dma-buf: align fd_flags and heap_flags with dma_heap_allocation_data 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.
