From 9a046c1d21f0ae14c73b5e106e5a501dd902b6a9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 9 Apr 2025 14:22:55 +0200 Subject: [PATCH] Input: stmpe-ts - use module alias instead of device table When compile tested with W=1 on x86_64 with driver as built-in: stmpe-ts.c:371:34: error: unused variable 'stmpe_ts_ids' [-Werror,-Wunused-const-variable] Ideally this would be referenced from the platform_driver, but since the compatible string is already matched by the mfd driver for its parent device, that would break probing. In this case, the of_device_id table just serves as a module alias for loading the driver, while the device itself is probed using the platform device name. Remove the table and instead use a module alias that reflects how the driver is actually probed.
