| |
2.6.28-stable review patch. If anyone has any objections, please let us know.
------------------
From: Larry Finger <Larry.Finger@lwfinger.net>
commit 58607b30fc0f2230a189500112c7a7cca02804cf upstream.
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.
