Serge Semin a41b0ad07b spi: dw: Set transfer handler before unmasking the IRQs ... It turns out the IRQs most like can be unmasked before the controller is enabled with no problematic consequences. The manual doesn't explicitly state that, but the examples perform the controller initialization procedure in that order. So the commit da8f58909e ("spi: dw: Unmask IRQs after enabling the chip") hasn't been that required as I thought. But anyway setting the IRQs up after the chip enabling still worth adding since it has simplified the code a bit. The problem is that it has introduced a potential bug. The transfer handler pointer is now initialized after the IRQs are enabled. That may and eventually will cause an invalid or uninitialized callback invocation. Fix that just by performing the callback initialization before the IRQ unmask procedure.
