[PATCH 0/4] crypto: Port ecc.c fixes from kernel

[Jonas Rebmann <jre@pengutronix.de>]

We've been working on processes for porting fixes from copied code in
winter and introduced Origin-URL references [1] during those
discussions.

Now thanks to Lukas we're reminded to put this to practice.

This series is a proposal on future standard practice of porting such
patches: Update the Origin-URL in every ported patch, mention the origin
project in the "cherry picked from" line. Handle like a backport for all
other regards.

Note that the most recent ported patch is linux commit c66e0a273f22
("crypto: ecc - Streamline alloc_point and remove
{alloc,free}_digits_space") but Origin-URL is pointing at commit
d6ea871d73ab ("crypto: ecc - Use crypto_stdrng_get_bytes()"), which I
intentionally skipped when porting as not applicable to barebox (we have
a different random bytes API). This is so that the file is now
recognizable as up to date until further updates on linux master.

To establish these processes, we should soon underscore them with some
tooling like Ahmad did in [1].
