How do you think about to try the following small script for the semantic patch
language out on the directory “drivers/phy/tegra”?

@display@
expression object;
identifier exit;
@@
 ... when any
 object = kzalloc(...)
 ...
 if (...)
 {
*kfree(object);
 goto exit;
 }
 ...
 if (...)
*   goto unregister;


Will any search pattern variations become more interesting for corresponding
automatic software transformations?
