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 Patch 2 cleans up some outdated documentation which was discovered while working on the earlier patches.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!
