Subject: [PATCH] scsi: Use module_pcmcia_driver
Date: Sat, 4 Jul 2015 09:19:09 +0530 [thread overview]
Message-ID: <20150704034909.GA5052@vaishali-Ideapad-Z570> (raw)
Use module_pcmcia_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 pcmcia_register_driver(&x); }
@b depends on a@
identifier e, a.x;
@@
-static e(...) { pcmcia_unregister_driver(&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_pcmcia_driver;
@@
-module_exit(e);
+module_pcmcia_driver(x);
