With 2.3.99-pre6 and 8 I still had problems with incorrect voltage on
cardbus cards, and the patch included in this post fixed it.

This is a simple, one-line patch. I believe that is corrects an important bug
in the PCMCIA cardbus code that resulted in incorrect voltage being applied to
3.3 Volt Cardbus cards on computers with a Texas Instruments PCI1221 cardbus
(and probably other models) bridge. The fix is quite obvious; the status of
a cardbus socket must be obtained using cb_readl, not config_readl since the
latter reads the pci config (using pci_read_config_dword). It should fix
voltage problems with other cardbus bridges that only supply the correct
voltage parameters in the status after a forced CB_CVSTEST.
