Hi Miqu?l,
Thanks for your work! If/when you post a v2, please run "git log
--oneline" and adjust your subject lines to match the capitalization
conventions, i.e., for PCI, start the description with a capital
letter: "PCI: aardvark: Add suspend to RAM support".
BTW, I notice you closed your email with "Miqu?l", but the patches
contain "Miquel". you *should* be able to use the correctly accented
version of your name in the Signed-off-by lines. I have tripped over
some tool issues, but if we pay attention, we should be able to get it
to work.
