Re: [PATCH v2 0/4] New Microsemi PCI Switch Management Driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

We're still waiting on any kind of response from Bjorn. (If you're
listening please say something!)

Does anyone have any suggestions for dealing with an unresponsive
maintainer? Or a way for us to move forward with this quickly and get it
merged?

ie. Can anyone else pick this up through another route? In the end, it's
just a fairly basic driver and doesn't touch any core PCI functionality
and we've had a fair amount of review from other kernel contributors,
all of which we've addressed.

Thanks,

Logan
