Subject: b43legacy: Fix error due to MMIO access with SSB unpowered
From: Larry Finger <[email protected]>
commit 8f4b20388fa77226a3605627a33a23f90d559e50 upstream.
There is a dummy read of a PCI MMIO register that occurs before the SSB bus
has been powered, which is an error. This bug has not been seen earlier,
but was apparently exposed when udev was updated to version 182.
