The auxdisplay Kconfig is confusing. It creates two separate menus even though the settings are closely related. Moreover, the options for setting the boot message depend on CONFIG_PARPORT even though they are used by drivers that do not. Clear up the confusion by moving the "Parallel port LCD/Keypad" menu under auxdisplay where it logically belongs. Change the boot message options to depend only on CONFIG_CHARLCD, making them accessible also when only the HD44780 is selected. Since the "Parallel port LCD/Keypad" driver now has a new dependency on CONFIG_AUXDISPLAY, rename its Kconfig symbol and keep the old one such that make oldconfig will not disable the driver.

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 Restructured Text 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.
