The main motivation for this series is to convert
i2c_setup_smbus_alert() to a function which returns an ERRPTR instead of
NULL. Because there are only a few driver using this function they are
all converted in one go (patch 1). The function is also renamed to make
sure out-of-tree users will note they have to update (or better
upstream). Patch 2 cleans up some outdated documentation which was
discovered while working on the earlier patches.

Changes since V1:
- used PTR_ERR_OR_ZERO in one place (thanks buildbot)
- better name of the new function (thanks Jean, Robert, and Luca for the
  discussion)
- one patch dropped from the old series, no need anymore to keep the
  function names in sync

Patches are on top of v5.6-rc3 and can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/i2c/new_client_device

Only build tested. Testing and reviews from people actually using SMBus
alert would be much appreciated!

Thanks,

   Wolfram
