Subject: [PATCH 4.19 88/93] memstick: jmb38x_ms: Fix an error handling path in jmb38x_ms_probe()

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

commit 28c9fac09ab0147158db0baeec630407a5e9b892 upstream.

If 'jmb38x_ms_count_slots()' returns 0, we must undo the previous
'pci_request_regions()' call.

Goto 'err_out_int' to fix it.

Fixes: 60fdd931d577 ("memstick: add support for JMicron jmb38x MemoryStick host controller")
