mmc: davinci: Don't strip remove function when driver is builtin
[ Upstream commit 55c421b364482b61c4c45313a535e61ed5ae4ea3 ]
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)
Fixes: b4cff4549b7a ("DaVinci: MMC: MMC/SD controller driver for DaVinci family")
