| |
At some point since 2.6.22, the aha152x_cs driver stopped working and started erring on load with the following messages:
kernel: pcmcia: request for exclusive IRQ could not be fulfilled. kernel: pcmcia: the driver needs updating to supported shared IRQ lines.
With the following change, the driver works with shared IRQs.

Juergen,
If you are not the correct person to receive this, please pass it on. I originally sent it to Dominik Brodowski, but heard nothing from him.
Thanks,
Larry ---
