I'm trying to compile gentoo-sources-4.0.0 and I am getting the following errors: ERROR: "regmap_irq_get_domain" [drivers/mfd/rt5033.ko] undefined! ERROR: "regmap_add_irq_chip" [drivers/mfd/rt5033.ko] undefined! Searching for that over the internet I found a patch that I think will be merged, but want to post it here so it can be applied before then: https://lkml.org/lkml/2015/3/5/247
This is in the genpatches repository for the next release of the 4.0 gentoo-sources kernel.
