Bug#1050352: backside USB-ports stop working after some time

[Rolf Reintjes <lists.rolf@reintjes.nrw>]

I am on testing.

I could isolate the problem causing code in the debian patches on file

drivers/iommu/intel/iommu.c

With this change

rolf@i7-5820K-debian-testing:~/kernel/linux-source-6.4/drivers/iommu/intel$ 
diff iommu.c.debian iommu.c
286c286
< int dmar_disabled = IS_ENABLED(CONFIG_INTEL_IOMMU_DEFAULT_OFF);
---
> int dmar_disabled = !IS_ENABLED(CONFIG_INTEL_IOMMU_DEFAULT_ON);

the problem is not there.
