dmaengine: lpc18xx-dmamux: fix device leak on route allocation
In the Linux kernel, the following vulnerability has been resolved: dmaengine: lpc18xx-dmamux: fix device leak on route allocation Make sure to drop the reference taken when looking up the DMA mux platform device during route allocation. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.
