usb: musb: musbhsdma: fix IRQ check dma_controller_create() in this MUSB DMA driver only regards 0 as a wrong IRQ number, despite platform_get_irq_byname() that it calls returns -ENXIO in that case. It leads to calling request_irq() with a negative IRQ number, and when it naturally fails, the following is printed to the console: request_irq -6 failed! and the DMA controller is not created. Fix this function to filter out the error values as well as 0. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
