From 39bd68d422ba085997fb1f26160d7c686915b3cb Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sun, 1 Oct 2023 01:43:38 +0200 Subject: Input: cap11xx - cache hardware ID registers The cap11xx devices have three hardware identification registers which are currently marked as volatile, preventing caching of those registers. This is not ideal since the registers should never change at runtime, we should be able to cache the value after the first read. Stop marking the registers as volatile, we don't have register defaults specified in the driver so this will result in reading from the hardware on first use.
