Subject: "sky2: set VPD size" triggers card recognition failure
We have reports[1] of sky2 cards failing to be recognised with the latest
2.6.30-rc8 kernels. We are seeing what appears to be failures to
obtains the chip id correctly:
sky2 driver version 1.22
sky2 0000:02:00.0: enabling device (0000 -> 0003)
sky2 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
sky2 0000:02:00.0: setting latency timer to 64
sky2 0000:02:00.0: Can't set VPD size
sky2 0000:02:00.0: unsupported chip type 0xff
sky2 0000:02:00.0: PCI INT A disabled
sky2: probe of 0000:02:00.0 failed with error -95
Based on the VPD size failure message we reverted just the commit below,
which restored the card:

sky2: set VPD size
Read configuration register during probe and use it to size the
available VPD. Move existing code using same register slightly
earlier in probe handling.
