0682e005d1 uio: uio_fsl_elbc_gpcm: convert platform driver to use dev_groups
Platform drivers now have the option to have the platform core create
and remove any needed sysfs attribute files.  So take advantage of that
and do not register "by hand" a sysfs group of attributes.

19f8d67fc6 uio: uio_fsl_elbc_gpcm: Make dev_attr_reg_br and dev_attr_reg_or static
Fix sparse warnings:

drivers/uio/uio_fsl_elbc_gpcm.c:71:1: warning:
 symbol 'dev_attr_reg_br' was not declared. Should it be static?
drivers/uio/uio_fsl_elbc_gpcm.c:72:1: warning:
 symbol 'dev_attr_reg_or' was not declared. Should it be static?

24438e4626 uio: uio_fsl_elbc_gpcm: simplify getting .driver_data
We should get 'driver_data' from 'struct device' directly. Going via
platform_device is an unneeded step back and forth.

0952c57c8f uio: Convert to using %pOFn instead of device_node.name
In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

f4eebb60a3 uio: uio_fsl_elbc_gpcm: Remove owner assignment from platform_driver
Structure platform_driver does not need to set the owner field, as this
will be populated by the driver core.

0049ef9c8d uio: uio_fsl_elbc_gpcm: Fix module autoload for OF platform driver
This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

d12f569c9b 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);
