[PATCH 0/3] i2c: updates to SMBus alert setup

From: Wolfram Sang
Date: Mon Feb 10 2020 - 12:29:32 EST


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 renames the of-equivalent, too, so both functions
keep in sync. Patch 3 cleans up some outdated documentation which was
discovered while working on the earlier patches.

Patches are on top of v5.6-rc1 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
