Hi! There are a couple of users that could benefit from an unlocked variant of i2c_smbus_xfer. In response to [1] I dusted off an old series that I have had in a branch for a while that adds such a beast. It also converts over some users in the i2c-mux department. There are a couple of remaining candidates in i2c/busses/i2c-amd756-s4882.c and i2c/busses/i2c-nforce2-s4985.c, but frankly, those are just too nasty. Why do they unregister the root adapter and then continue to use it? I dare not touch that code... Anyway, this series looks like a nice cleanup to me, and the recent sccb patch from Akinobu Mita could also benefit, as indicated by Wolfram [1].
