Make this explicit to prevent a section mismatch warning: WARNING: modpost: drivers/platform/x86/hp/hp-wmi: section mismatch in reference: hp_wmi_driver+0x8 (section: .data) -> hp_wmi_bios_remove (section: .exit.text) Fixes: c165b80cfecc ("hp-wmi: fix handling of platform device") Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20231004111624.2667753-1-u.kleine-koenig@pengutronix.de Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede --- diff --git a/drivers/platform/x86/hp/hp-wmi.c b/drivers/platform/x86/hp/hp-wmi.c index e76e545..8ebb7be 100644 --- a/drivers/platform/x86/hp/hp-wmi.c +++ b/drivers/platform/x86/hp/hp-wmi.c @@ -1548,7 +1548,13 @@ static const struct dev_pm_ops hp_wmi_pm_ops = { .restore = hp_wmi_resume_handler, }; -static struct platform_driver hp_wmi_driver = { +/* + * hp_wmi_bios_remove() lives in .exit.text.
