From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

A wrong use of one of these in
https://lore.kernel.org/linux-iio/20210514135927.2926482-1-arnd@kernel.org/ (local)
included a reference from Nathan to a patch discouraging the use of
these strings in general:

I did a quick grep and established we only have a few instances of these in
IIO anyway, so in the interests of avoiding those existing cases getting
cut and paste into new drivers, let's just clear them out now.

Note that patch from Arnd is now also part of this series, due to the
length specifier related issue Joe raised.

I have chosen to go with 0x%02x rather than %#04x as I find it more readable.

V2:
Use 0x%02x (Joe Perches)
Include Arnd's original patch, modified for the above.

Arnd Bergmann (1):
  iio: si1133: fix format string warnings

Jonathan Cameron (3):
  iio: light: si1133: Drop remaining uses of %hhx format string.
  iio: imu: inv_mpu6050: Drop use of %hhx format string.
  iio: light: si1145: Drop use of %hhx format specifier.
