[RFC BUG] pci: Freescale i.MX6 PCIe controller: revert mainline regression
From: Sven Van Asbroeck
Date: Tue Dec 18 2018 - 16:05:03 EST
We are using a Broadcom BCM57780 ethernet adapter (Tigon3) connected
to a i.MX6 PCIe controller. On a Freescale i.MX6 SoC.
This combo worked ok on mainline v4.17.
On mainline v4.18-rc1, a regression was introduced that caused a crash.
This regression is still present in current mainline as of v4.20-rc7
Bisected the regression to the following merge head:
commit 0ecda3a08746 ("Merge branch 'pci/kconfig'")
When this merge head is removed, the regression disappears. This commit
reverts the changes introduced by the offending merge head.
Crash message:
