3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christoph Biedl <linux-kernel.bfrz@xxxxxxxxxxxxxxxxxx> commit 3460baa620685c20f5ee19afb6d99d26150c382c upstream. Commit 36e097a8a297 ("PCI: Split out bridge window override of minimum allocation address") claimed to do no functional changes but unfortunately did: The "min" variable is altered. At least the AVM A1 PCMCIA adapter was no longer detected, breaking ISDN operation. Use a local copy of "min" to restore the previous behaviour.
