'cxl_dev_context_init()' returns an error pointer in case of error, not
NULL. So test it with IS_ERR.

un-compiled because I don't have the required cross build environment.

Builds fine here.
In future, you might want to bundle all 3 of your patches either into 1
patch (while they are changes which can be done separately, it's all
fixes to one type of problem in relation to one function, so personally
I'm okay with that) or send it as a series, so that it's clear to
everyone that they're all related fixes.
Additionally, having the same patch subject line for two patches sent in
short succession is a bit confusing - in future, try and avoid that.

Yeah. I actually assumed it was two versions of the same patch.
