Constify a number of static structs to allow the compiler to put them in
read-only memory. The patches are independent.

Rikard Falkeborn (6):
  iio: adc: max11100: Constify struct iio_chan_spec
  iio: dac: ad5380: Constify struct iio_chan_spec_ext_info
  iio: dac: ad5592r-base: Constify struct iio_chan_spec_ext_info
  iio: dac: ad5686: Constify static struct iio_chan_spec
  iio: light: stk3310: Constify regmap_config
  iio: magnetometer: mmc35240: Constify struct reg_default

These are never modified and can be made const to allow the compiler to
put it in read-only memory.

Before:
   text    data     bss     dec     hex filename
   6642   12608      64   19314    4b72 drivers/iio/dac/ad5686.o

After:
   text    data     bss     dec     hex filename
  16946    2304      64   19314    4b72 drivers/iio/dac/ad5686.o

Was this one really applied? I can't see it anywhere? The rest of the
patches in the series are in Linus' tree.
