Subject: [Cocci] Checking adjustments for pointer resets with SmPL
Date: Mon, 21 Sep 2020 17:34:52 +0200 [thread overview]
Message-ID: <17fe1cf3-c85c-971d-8e59-65b666e91071@web.de> (raw)
Hello,
I have noticed the update suggestion “USB: quirks: simplify quirk handling”.
https://lore.kernel.org/linux-usb/20200921113039.GA19862@duo.ucw.cz/
https://lore.kernel.org/patchwork/patch/1308991/
Thus I converted a patch hunk into the following script variant for
the semantic patch language (according to the software “Coccinelle 1.0.8-00177-g28737419”).
@adjustment@
identifier allocate, object, release;
@@
-if (object)
-{
-release(object);
-object = NULL;
-}
+release(object);
object = allocate(..., sizeof(...), ...);
Now I wonder at the moment why a known patch is not generated.
(An error message is not displayed.)

Regards,
Markus
