From 3b018391b6158039ee459c9d8ce203fed408cf51 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 7 Dec 2023 15:09:29 +0100 Subject: hwmon: (smsc47m1) Mark driver struct with __refdata to prevent section mismatch As described in the added code comment, a reference to .exit.text is ok for drivers registered via module_platform_driver_probe(). Make this explicit to prevent the following section mismatch warning WARNING: modpost: drivers/hwmon/smsc47m1: section mismatch in reference: smsc47m1_driver+0x8 (section: .data) -> smsc47m1_remove (section: .exit.text) that triggers on an allmodconfig W=1 build.
