Thanks for taking care of this. 

I just got a new testing device with RTL9313 on my desk with which I could test
the two-master functionality. Thanks to this, I noticed a bug in the last patch of
my series before it is merged completely.

Due to a misunderstanding of how 'device_property_read_u8' works and that it
does not read '1' out of 'realtek,scl = <1>;' in the device tree, the second
master didn't work.

How is the usual way to proceed on this? Should I just resubmit my patchset,
except the first 3 patches you already merged in your tree, to have that fix?
