dmaengine: mxs: remove NO_IRQ check
The mxs_chan->chan_irq variable is guaranteed to never be NO_IRQ, as it gets assigned the result of platform_get_irq() that returns either a valid positive interrupt number, or a negative failure code that leads to the channel not being used. This removes the redundant check, eliminating one more instance of NO_IRQ. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
