[PATCH 04/12] i2c: mux: populate the new *_atomic callbacks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If the parent adapter has atomic_xfer callbacks, populate them for the
mux adapter as well. We can use the same translation function as for the
non-atomic xfer callback.
