scsi: Use module_pcmcia_driver

Commit Message

Vaishali Thakkar July 4, 2015, 3:49 a.m. UTC

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);
