From: Yoshihiro Shimoda yoshihiro.shimoda.uh@renesas.com Date: Fri, 6 Nov 2020 18:25:30 +0900 Subject: [PATCH] mmc: renesas_sdhi_core: Add missing tmio_mmc_host_free() at remove MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
The commit 94b110aff867 ("mmc: tmio: add tmio_mmc_host_alloc/free()") added tmio_mmc_host_free(), but missed the function calling in the sh_mobile_sdhi_remove() at that time. So, fix it. Otherwise, we cannot rebind the sdhi/mmc devices when we use aliases of mmc.
