This series adds a dev_errp_probe() helper. This is similar to
dev_err_probe() but for cases where an ERR_PTR() is to be returned
simplifying patterns like:
dev_err_probe(dev, ret, ...);
return ERR_PTR(ret)
The other three patches are adding users for it. The main motivator for
this were the changes in the commit ("iio: temperature: ltc2983: convert
to dev_err_probe()"). Initially I just had a local helper [1] but then
it was suggested to try a new, common helper. As a result, I looked for
a couple more users.
I then move into dev_errp_probe() [2] but it was then suggested to separare
the patch series so we have onde dedicated for the printk helper.
