Subject: kabi: PCI: endpoint: Fix for concurrent memory allocation in OB
 address region
Patch-mainline: never, kabi
References: git-fixes

Commit 04e046ca57eb (PCI: endpoint: Fix for concurrent memory allocation
in OB address region) added a mutex to struct pci_epc_mem. That struct
is allocated only in __pci_epc_mem_init(). And the struct is referenced
only by a pointer in struct pci_epc.

So hide the change by usual __GENKSYMS__ #ifdef.
