Re: [linusw-pinctrl:for-next] BUILD REGRESSION 0c3c8458428ab471178a0d155222eaa62083d033

Hi Jonathan,

this driver just keeps creating new sparse warnings, I try to fix them
but I wonder
if new warnings will result everytime I fix something?

Do you think you could run sparse over the drivers in some way and check
what else needs to be fixed?

Yours,
Linus Walleij
