Hello Adam and other.
I've just posted another patch that works for PnP cards to you and Samium.
During the work on it, i've found some bugs, but I can't solve them.
At the end of patch there is hack for drivers/pnp/driver.c look at it.
devs - member of pnp_card_device_id struct have got more then one id for
awe32 cards and when we request first device with
const char *id=devs[0].id it contains "CTL0031CTL0021" instead "CTL0031"
and compare_pnp_id fails on it.
This bug can be solved in other way with allocation tmp buffer in driver,
copy id from table to buffer, add to the end \0 then request for device,
but I think that it's bad way.
Any suggestions?
And next:
if probe function fails for some reasons. PnP layer does not do all clean
ups as i think. Because just after it I do the same command and ko loads
with oops. Some points on it:
1) pnpc_driver has been registered, but after drv->probe fail, it's not
been unregistered.
2) There is was some patch in 2.5.59 to driver-model that changed
something and it's may be a reason, I don't know exactly.
Best regards, Ruslan.
