Subject: [PATCH] iwlwifi: pcie: fix erroneous "Read failed message"
Git-commit: f3402d6d8eb084f6c2563dee1a09385b7c0ea2d5
Patch-mainline: v4.15-rc3
References: FATE#326294
Current pci dumping code code is always falling to the error
path, resulting with a constant "Read failed" message, also
for the successful reads.
