[PATCH v3 0/6] sysctl: Remove register_sysctl_table from parport

[Joel Granados]

This is part of the general push to deprecate register_sysctl_paths and
register_sysctl_table. Parport driver uses the "CHILD" pointer
in the ctl_table structure to create its directory structure. We move to
the newer register_sysctl call and remove the pointer madness.

I have separated the parport into 5 patches to clarify the different
changes needed for the 3 calls to register_sysctl_paths. I can squash
them together if need be.

We no longer export the register_sysctl_table call as parport was the
last user from outside proc_sysctl.c. Also modified documentation slightly
so register_sysctl_table is no longer mentioned.

V2:
* Added a return error value when register fails
* Made sure to free the memory on error when calling parport_proc_register
* Added a bloat-o-meter output to measure bloat
* Replaced kmalloc with kzalloc
* Added comments about testing
* Improved readability when using snprintf

Best
