For Logic PD distributions, we create a custom defconfig with all those drivers removed, so I'm not worked up about it, but it would be nice to not call drivers that don't exist. > > The hang happens at an odd time.

Thanks for reviewing this. I've been coping for a while by manually changing the config option, but with 5.4 being the expected next LTS, I was hoping to address this so I don't have to keep working around it. > > You could try adding an extra call to dss_runtime_get().

I'll send out a second e-mail with some of your suggestions, but I don't want to litter this e-mail with too many logs. adam > > Tomi > > -- > Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki. > Y-tunnus/Business ID: 0615521-4.
