[Qemu-devel] [PATCH 1/2] dma-helpers: Initialize DMAAIOCB in_cancel flag

[Peter Maydell]

Initialize the dbs->in_cancel flag in dma_bdrv_io(), since qemu_aio_get()
does not return zero-initialized memory. Spotted by the clang sanitizer
(which complained when the value loaded in dma_complete() was not valid
for a bool type); this might have resulted in leaking the AIO block.
