      I've no idea why this driver uses NULL for dma_unmap_single instead of
      the &spi->dev that is laying around just waiting to be used in that
      function - but it's an easy fix.
      
      Also replace this comment with a FIXME comment:
                      /* Do DMA mapping "early" for better error reporting and
                       * dcache use.  Note that if dma_unmap_single() ever starts
                       * to do real work on ARM, we'd need to clean up mappings
                       * for previous transfers on *ALL* exits of this loop...
                       */
      as the comment is not true - we do work in dma_unmap() functions,
      particularly on ARMv6 and above.  I've corrected the existing unmap
      functions but if any others are required they must be added ASAP.

      spi/imx: correct the test on platform_get_irq() return value · 73575938
      Richard Genoud authored
      The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but
      the return value of platform_get_irq().  As platform_get_irq() can
      return an error (-ENXIO) or the IRQ value it found, the test should be
      "if (spi_imx->irq < 0)"
      
      [grant.likely: Note: In general, Linux irq number 0 should also mean
      no irq, but arm still allows devices to be assigned 0, and the imx
      platform uses 0 for one of the spi devices, so this patch is needed
      for the device to work]

      sched: Constify function scope static struct sched_param usage · c9b5f501
      Peter Zijlstra authored
      Function-scope statics are discouraged because they are
      easily overlooked and can cause subtle bugs/races due to
      their global (non-SMP safe) nature.
      
      Linus noticed that we did this for sched_param - at minimum
      make the const.

      sched: Fix strncmp operation · 524429c3
      Hillf Danton authored
      One of the operands, buf, is incorrect, since it is stripped and the
      correct address for subsequent string comparing could change if
      leading white spaces, if any, are removed from buf.
      
      It is fixed by replacing buf with cmp.
