ML1. If you build a topology with a mux-locked mux being the parent

collisions between the devices on the child adapters of these
non-sibling muxes.

Parent-locked muxes

transfer-deselect transaction. The implication is that the mux driver
has to ensure that any and all I2C transfers through that parent
adapter during the transaction are unlocked I2C transfers (using e.g.
__i2c_transfer), or a deadlock will follow. There are a couple of
caveats.

PL1. If you build a topology with a parent-locked mux being the child
of another mux, this might break a possible assumption from the
child mux that the root adapter is unused between its select op
and the actual transfer (e.g. if the child mux is auto-closing

This is especially the case if the parent mux is mux-locked, but
it may also happen if the parent mux is parent-locked.
PL2. If select/deselect calls out to other subsystems such as gpio,
pinctrl, regmap or iio, it is essential that any I2C transfers
caused by these subsystems are unlocked. This can be convoluted to
accomplish, maybe even impossible if an acceptably clean solution
