dma-mapping: fix direction in dma_alloc direction traces

[PATCH] dma-mapping: fix direction in dma_alloc direction traces

Posted by Petr Tesarik 14 hours ago

Set __entry->dir to the actual "dir" parameter of all trace events
in dma_alloc_class. This struct member was left uninitialized by
mistake.
