Subject: [PATCH 3.16 049/136] memstick: jmb38x_ms: Fix an error handling
 path in 'jmb38x_ms_probe()'

3.16.80-rc1 review patch.  If anyone has any objections, please let me know.

------------------

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.
