[PATCH 5.10 029/299] mmc: uniphier-sd: Fix a resource leak in the remove function

From: Greg Kroah-Hartman
Date: Mon May 10 2021 - 06:51:29 EST

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

commit e29c84857e2d51aa017ce04284b962742fb97d9e upstream.

A 'tmio_mmc_host_free()' call is missing in the remove function, in order
to balance a 'tmio_mmc_host_alloc()' call in the probe.
This is done in the error handling path of the probe, but not in the remove

Add the missing call.
