From e81bb6f59b35adae545162928bc7a80cb01cda0f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 29 Mar 2024 22:11:41 +0100 Subject: [PATCH] scsi: a3000: Mark driver struct with __refdata to prevent section mismatch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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/scsi/a3000: section mismatch in reference: amiga_a3000_scsi_driver+0x8 (section: .data) -> amiga_a3000_scsi_remove (section: .exit.text) that triggers on an allmodconfig W=1 build.
