[PATCH 0/3] hwmon: (various) add missing `select REGMAP` to Kconfig

[Joshua Crofts]

This series adds missing `select REGMAP` and `select REGMAP_I2C` to the
MAX6679/MAX1619/LTC2992 Kconfig entries. Without these, some builds may
result in a failure.

Steps to reproduce build failure:
1. Run `make allnoconfig`.
2. Run `make menuconfig` and select I2C, hwmon and any of said drivers.
3. Run `make .` and make will end with regmap-related errors.

[PATCH 1/3] hwmon: (max1619) add missing 'select REGMAP' to Kconfig

[Joshua Crofts]

The Kconfig entry for the MAX1619 sensor doesn't contain a
`select REGMAP` parameter, causing build failures if regmap
isn't selected previously during the build process.

Author: Joshua Crofts <joshua.crofts1@gmail.com>

hwmon: (max6679) add missing 'select REGMAP_I2C' to Kconfig

This commit adds a missing REGMAP_I2C selection to a Kconfig entry to prevent
potential build failures when regmap has not been previously selected.

[Severity: Low]
This isn't a bug, but there appears to be a typo referencing max6679 and
MAX6679 in the commit subject and body. The code changes modify the entry for
SENSORS_MAX6697, and the Fixes tag also correctly notes max6697. Should the
commit message be updated to max6697 to accurately reflect the configuration it
modifies?

Oops, typo in the commit message, it should be 6697 in the title and
body. Shall I send
a new version or can it be tweaked when applying?

Applied, after fixing 6679 --> 6697.
