Subject: uio: uio_fsl_elbc_gpcm: Use module_platform_driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d12f569c9b57ecdb18631d0b54c5224da5a1c233;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

uio: uio_fsl_elbc_gpcm: Use module_platform_driver

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);
