Vignesh Raghavendra 935da5e510 mtd: spi-nor: cadence-quadspi: Handle probe deferral while requesting DMA channel ... dma_request_chan_by_mask() can throw EPROBE_DEFER if DMA provider is not yet probed. Currently driver just falls back to using PIO mode (which is less efficient) in this case. Instead return probe deferral error as is so that driver will be re probed once DMA provider is available.
