[PATCH 0/1] Fix bug resulting in double hpmemsize being assigned to MMIO window

[Nicholas Johnson]

I have split this patch off my main series, as I realised that it does 
not need to be part of that series.

I have made some recent improvements to add assurance against it 
breaking existing behaviour. Instead of returning the first resource of 
the desired type regardless of it being assigned, now it goes through 
all of the resources and returns only those of type that are not 
assigned. Only then does it go through and return the first resource of 
desired type that is assigned. If none are found then it returns NULL as 
usual.

I have made extensive changes to the patch notes, also.

Logan Gunthorpe <logang@xxxxxxxxxxxx> has an alternative method of 
fixing this same bug. Please also consider his patch and accept 
whichever is best for Linux. All I care is that the bug be fixed.
