From 09ac57ac01e16268de9677728606c68d8d513d3a Mon Sep 17 00:00:00 2001 From: Dumitru Ceclan Date: Tue, 20 Feb 2024 17:34:51 +0200 Subject: iio: amplifiers: hmc425a: use pointers in match table Change the match table to use pointers instead of device ids. Remove type from state as it is not used anymore. Also make the chip_info structures const.
