Re: [PATCH v5 00/11] add pinmuxing support for pins in AXP209 and AXP813 PMICs

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

 




Hi all,

Copy pasting of the cover letter done wrong, there are only 9 patches in
this patch series unlike what's specified in the title of the cover
letter for this patch series.

Sorry for the noise.
