[-next] spi: xilinx: Use devm_platform_get_and_ioremap_resource()

  According to commit 890cc39a8799 ("drivers: provide
devm_platform_get_and_ioremap_resource()"), convert
platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Thanks!

[1/1] spi: xilinx: Use devm_platform_get_and_ioremap_resource()
      commit: 0623ec17c45ed3e96880453f69461d526dc97f41

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

So we keep the local var res just to print its value? Wouldn't have been
better to have something like:

diff --git a/drivers/spi/spi-xilinx.c b/drivers/spi/spi-xilinx.c

I would get rid of printing xspi->irq too, as I don't see any benefit in
printing it, but that would be for another patch, as it is a different
logical change.
