Re: [PATCH 2/2] mfd: max14577: Add device tree bindings document

[Tomasz Figa <t.figa-Sze3O3UU22JBDgjK7y7TUQ@public.gmane.org>]

Hi,

Oops, I have forgotten to add suppress-cc to git send-email and the 
series went outside the intended audience... Please disregard these patches.

Sorry for the noise.

Best regards,
Tomasz
