[PATCH 0/3] iio: pressure: dps310: fix input checks and resets

[Rupesh Majhi <zoone.rupert@gmail.com>]

Sashiko flagged these as pre-existing in its review of the FIFO series
v8 [1]. All three reproduce on a DPS310 on a BeagleBone Black:

- 0 or 0.5 written to a rate or ratio is accepted. Ratio 0 puts a
  reserved value in the register: pressure reads fail with -ERANGE,
  temperature reads 974 C.
- A warm reboot during a FIFO capture leaves FIFO_EN set. After it,
  every raw read times out until the driver is unbound.
- The reset after a read timeout silently puts the rate and ratio back
  to their defaults.

Patch 2 fixes a commit that is only in iio testing so far.

Paulius, patch 2 also resets the ZTS8032 at probe, the same reset that
remove already does. A Tested-by would be welcome if you have time.

Based on iio testing. Reproduced and fixed with help from an LLM coding
assistant.
