#4 lore raw

Hello, Adam and other.
Now with this changes, driver depend on CONFIG_PNP.
What to do if I want compile kernel without PnP layer and I want use my soundcard?
Best regards, Ruslan.

#5 lore raw
Quoted 5 lines · Ruslan U. Zakirov

Hello, Adam and other.
Now with this changes, driver depend on CONFIG_PNP.
What to do if I want compile kernel without PnP layer and I want use my soundcard?
Best regards, Ruslan.

Hi Ruslan,

I understand your concern, actually the code that prevents users from using als100 without CONFIG_PNP is hidden in kconfig.

config SND_ALS100
tristate "Avance Logic ALS100/ALS120"
depends on SND && ISAPNP
help
Say 'Y' or 'M' to include support for Avance Logic ALS100, ALS110, ALS120 and ALS200 soundcards.

--->Notice ISAPNP

Also the pnp functions are declared as blank inline functions if CONFIG_PNP isn't set (see pnp.h). This will prevent compile errors. When ALSA drivers contain support for both pnp and nonpnp devices (such as sb16), CONFIG_PNP will be used directly in the code.

Best regards to you as well.

Thanks,
Adam
