| |
Use module_platform_driver for drivers whose init and exit functions only register and unregister, respectively.
A simplified version of the Coccinelle semantic patch that performs this transformation is as follows:
@a@ identifier f, x; @@ -static f(...) { return platform_driver_register(&x); }
@b depends on a@ identifier e, a.x; @@ -static e(...) { platform_driver_unregister(&x); }
@c depends on a && b@ identifier a.f; declarer name module_init; @@ -module_init(f);
@d depends on a && b && c@ identifier b.e, a.x; declarer name module_exit; declarer name module_platform_driver; @@ -module_exit(e); +module_platform_driver(x);
