Subject: [PATCH 5.15 013/244] mmc: meson-gx: Fix an error handling path in meson_mmc_probe()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

commit b3e1cf31154136da855f3cb6117c17eb0b6bcfb4 upstream.

The commit in Fixes has introduced a new error handling which should goto
the existing error handling path.
Otherwise some resources leak.

Fixes: 19c6beaa064c ("mmc: meson-gx: add device reset")
