From: Wolfram Sang <wsa@xxxxxxxxxxxxx> In the on-going mission to let i2c_new_* calls return an ERR_PTR instead of NULL, here is a series converting i2c_new_probed_device(). A new function called i2c_new_scanned_device() is introduced with the new retval, but for now, a compatibility helper is provided until all users are converted. The rest of the patches convert all current in-tree users. Note that these patches are RFC because I want feedback on the approach and hopefully collect acks on the driver conversions. If all goes well, I'll apply the first two patches for the next merge window. Then, once this dependency is upstream, I'll resend this series with all issues fixed and acks collected. Core changes tested on a Renesas Salvator-XS board (R-Car M3-N), driver patches build tested by me and buildbot.
