[PATCH v9 0/5] Move Hisilicon 6421v600 SPMI and USB drivers out of staging

[Mauro Carvalho Chehab]

Hi Greg,

This series contain the final bits needed for the USB3 bus to work
without staging drivers on Hikey 970.

It takes a different approach from the past series: basically,
it moves all IRQ related stuff into a new driver ( hi6421v600-irq),
and the MFD driver (hi6421-spmi-pmic) is now quit simple:
it contains just probe and regmap, which attaches into
two MFD "child" drivers (a regulator driver and an IRQ one).

This series also fixes a sutile bug recently introduced via the
regulator tree (patch 2).

Basically, the SPMI/MFD driver combination already uses the
platform data, but the new patch re-uses it to store a mutex
instead, overlapping the previous usage.

This was unoticed on my past tests, as there were some
unused data at the platform struct, that were big enough
to store a mutex, but when I tried to remove it, it caused
crashes and instability at the board.

Regards,
Mauro
