Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and the error value gets printed.
There is also no need to assign NULL to 'intr->sci' as it is part of
devm-allocated memory.

I'm not sure that replacing a flaky variable name with something that
is essentially unintelligible is a huge improvement.

Without deviation from the norm, progress is not possible.

Applied to irq/irqchip-next, thanks!
[1/2] irqchip/ti-sci: Simplify with dev_err_probe()
commit: ea6c25e6057c0b7c18337696be84b8f9751f19ec
Patch #2 didn't make a lot of sense, so not applied.
Cheers,
M.
