Subject: [PATCH 0/6] spi: struct spi_device constification

	Hi all,

After noticing new cases of casting away constness, I went over all
spi_get_*() functions and their callers, and made the following changes:
  1. Make all pointer parameters const where possible,
  2. Remove unneeded casts, some not even related to constness.

Patches 1-5 do not have any dependencies.
Patch 6 depends on patch 5 (and current spi/for-next).

Thanks for your comments!

Geert Uytterhoeven (6):
  mfd: rsmu_spi: Remove unneeded casts of void *
  spi: fsl-dspi: Remove unneeded cast to same type
  spi: Constify spi_get_ctldata()'s spi parameter
  spi: Constify spi_get_drvdata()'s spi parameter
  spi: Constify spi parameters of chip select APIs
  spi: sh-msiof: Remove casts to drop constness

when I'm talking to journalists I just say "programmer" or something like that.
