2019-11-28i2c: replace i2c_new_probed_device with an ERR_PTR variantWolfram Sang1-4/+4
In the general move to have i2c_new_*_device functions which return ERR_PTR instead of NULL, this patch converts i2c_new_probed_device(). There are only few users, so this patch converts the I2C core and all users in one go. The function gets renamed to i2c_new_scanned_device() so out-of-tree users will get a build failure to understand they need to adapt their error checking code.
