Boris Brezillon 4a3e85f267 mtd: devices: m25p80: Make sure the buffer passed in op is DMA-able ... As documented in spi-mem.h, spi_mem_op->data.buf.{in,out} must be DMA-able, and commit 4120f8d158 ("mtd: spi-nor: Use the spi_mem_xx() API") failed to follow this rule as buffers passed to ->{read,write}_reg() are usually placed on the stack. Fix that by allocating a scratch buffer and copying the data around.
