6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König u.kleine-koenig@pengutronix.de
commit 55c421b364482b61c4c45313a535e61ed5ae4ea3 upstream.
Using __exit for the remove function results in the remove callback being discarded with CONFIG_MMC_DAVINCI=y. When such a device gets unbound (e.g. using sysfs or hotplug), the driver is just removed without the cleanup being performed. This results in resource leaks. Fix it by compiling in the remove callback unconditionally.
This also fixes a W=1 modpost warning:
WARNING: modpost: drivers/mmc/host/davinci_mmc: section mismatch in reference: davinci_mmcsd_driver+0x10 (section: .data) -> davinci_mmcsd_remove (section: .exit.text)
