  "message": "ARM: PL08x: fix atomic_t usage and tx_submit() return value range\n\nThe last_issued variable uses an atomic type, which is only\nincremented inside a protected region, and then read.  Everywhere else\nonly reads the value, so it isn\u0027t using atomic_t correctly, and it\ndoesn\u0027t even need to.  Moreover, the DMA engine code provides us with\na variable for this already - chan.cookie.  Use chan.cookie instead.\n\nAlso, avoid negative dma_cookie_t values - negative returns from\ntx_submit() mean failure, yet in reality we always succeed.  Restart\nfrom cookie 1, just like other DMA engine drivers do.\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nAcked-by: Linus Walleij \u003clinus.walleij@stericsson.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\n",
