Your software understanding evolved into another direction.

Can the following source code search pattern represent discussed development concerns
in a succinct way?

@display@
expression dev, e;
@@
*e = dev_err_probe(dev, e, ...)


The evaluation of such a tiny SmPL script can point out that 14 source files
of the software “Linux next-20251017” contain corresponding update candidates.
Will any adjustments become helpful also at these places?

Markus
