I hoped to achieve something together with the semantic patch language
by the following transformation approach.
@adjustment@
expression object;
identifier exit;
@@
object = kzalloc(...)
...
if (...)
-{ kfree(object);
goto
- exit
+ release_memory
;
-}
... when any
device_unregister(...);
-exit
+release_memory
:
+kfree(object);
return ERR_PTR(...);
Do you find such a change suggestion reasonable (in principle)?
But I stumble on another unexpected test result.

HANDLING: drivers/phy/tegra/xusb-tegra186.c
How would you like to clarify why diff hunks were not generated
for functions like “tegra186_usb2_pad_probe” and “tegra186_usb3_pad_probe”
in such an use case?
