I don't recall your report.  I might have just failed to read it, but
doing a quick mail search only finds "Subject: randconfig failures -
MMC + trusted foundations" -- which was sent to linux-arm-kernel@, but
not CC'd to linux-mmc@ or to me.

Furthermore, this error does not exist in mmc-next or linux-next,
so it's unclear why or how the MMC maintainers would fix it.
drivers/mmc/core/core.c does not use gpiod_set_value() in these trees.

Presumably you're testing Olof's unmerged patch "mmc: add support for
power-on sequencing through DT".  If it needs to include more gpio
headers, that should be reported to Olof for a respin.

The patch has not been merged because we're still discussing the best
way forward on linux-mmc@, in the thread "RFC: representing sdio
devices oob interrupt, clks, etc. in device tree".  The most recent
message in the thread is from yesterday.

- Chris.
