Sorry, it's the gmail threading that confuse the different patches.

The patch I actually applied is for gpio-sprd.c and looks like this:

commit 851f66daeab961328507dcce0980cd7e4ff5f9ae (HEAD -> devel)
Author: Enrico Weigelt, metux IT consult <info@metux.net>
Date: Mon Mar 11 19:55:08 2019 +0100

drivers: gpio: sprd: use devm_platform_ioremap_resource()

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.
