[PATCH 1/2] hwmon: (ina2xx) clean up unused macro and outdated comment

From: Jonas Rebmann

Date: Tue Mar 03 2026 - 06:08:51 EST


The list of supported chips in the header is incomplete and contains no
other information not readily available. Remove the list and instead
hint that the chips supported by this driver have 219/226 compatible
register layout [unlike the ones supported by e.g. ina238].

Remove the unused INA226_DIE_ID macro.
