The callback function dma_buf_describe() returns an int not void so the function pointer cast in dma_buf_show() is wrong. dma_buf_describe() can also fail when acquiring the mutex gets interrupted so always returning 0 in dma_buf_show() is wrong, too. Fix both issues by avoiding the indirection via dma_buf_show() and call dma_buf_describe() directly. Rename it to dma_buf_debug_show() to get it in line with the other functions. This type mismatch was caught by the PaX RAP plugin. Signed-off-by:
