[Acx100-devel] [PATCH] get rid of circular list of adev's

[Denis V. <vd...@il...>]

Hi folks,

If someone has cardbus acx, please test this one.

Basically, in acxpci_e_remove() we will check the presence
of the card by reading a register and if it is not all ones,
we will command device to shut down.

Previously it was done in acxpci_e_cleanup_module().

+INLINE_IO int
+adev_present(acx_device_t *adev)
+{
+       /* fast version (accesses the first register, IO_ACX_SOFT_RESET,
+        * which should be safe): */
+       return readl(adev->iobase) != 0xffffffff;
+}
