[PATCH] hwmon: (max6639) Publish the OF module alias

[hpp.iscas]

The MAX6639 I2C driver matches Device Tree devices through
max6639_of_match, but only publishes its I2C ID table. The I2C core
emits an OF modalias for a Device Tree client, which does not match
the legacy i2c:max6639 alias.

Publish the existing OF table; retain legacy I2C detection.

Fixes: f11e27383c12 ("hwmon: (max6639) Add compatible string")
