Re: [PATCH] nouveau, ACPI: fix regression caused by b072e53

On some platforms, ACPI _DSM method (nouveau_op_dsm_muid, function 0) has special requirements on the fourth parameter, which is different from ACPI specifications. So revert to the private implementation to check availability of _DSM functions instead of using common acpi_check_dsm() interface.

Hi Maarten, Thanks for bisecting. Could you please help to verify whether this patch fixes the regression?

I was wrong about the operator precedence, seems correct after all. :-)
