joycon_leds_create() has a ida_alloc() call. So if an error occurs after
it, a corresponding ida_free() call is needed, as already done in the
.remove function.
This is not 100% perfect, because if ida_alloc() fails, then
'ctlr->player_id' will forced to be U32_MAX, and an error will be logged
when ida_free() is called.
Considering that this can't happen in real life, no special handling is
done to handle it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
