[PATCH v3 0/6] ti-ads7950: fix gpio handling and facelift

[Dmitry Torokhov]

The original reason for this series is to make sure ti_ads7950_get()
returns result in range [0, 1] or a negative error code to comply with
gpiolib requirement.

During review David noticed the fact that the function also clobbers
gpio state. Fixing that lead to adding cleanups using guard() and devm.

v3:

- Added "Fixes" tags
- Picked up reviewed-by tags for #1 and #2
- Dropped the conversion to "error" variables
- Avoid using scoped_guard (per David)
- directly return results of function calls at the end of function (David)
- Split spi_sync() error handling into a new patxch (Andy)
- Switch to using devm_regulator_get_enable_read_voltage() (David)

v2:

- style fixes in #1 (per David)
- fix to not clobber state (#2, new)
- #3 and #4 (new)
