The issue I saw is that writing to GPIO has no effect. On my device
(mt7620-based), I can control the power to the two mini-pcie slots by
writing to /sys/class/gpio/power_pcie{1,2}/value. After the commit
"ramips: mmc: Sync with
staging driver", writing to these two files have no effect. I.e., I
can no longer control the power.

I see I used the wrong has in my original email, the correct sha of
the commit is fec205f6544a.
