Subject: [PATCH 0/5] i2c: smbus: add unlocked __i2c_smbus_xfer variant
Date: Wed, 20 Jun 2018 10:51:52 +0200 [thread overview]
Message-ID: <20180620085157.30121-1-peda@axentia.se> (raw)
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].
Cheers,
Peter
