[PATCH] scsi: Use module_pci_driver
From: Vaishali Thakkar
Date: Wed Jul 08 2015 - 00:32:32 EST
Use module_pci_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 pci_register_driver(&x); }
@b depends on a@
identifier e, a.x;
@@
-static e(...) { pci_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_pci_driver;
@@
-module_exit(e);
+module_pci_driver(x);
