Johan Hovold 1d9cde4ddf tty: fix return value for unsupported termiox ioctls [ Upstream commit `8871de06ff` ] Drivers should return -ENOTTY ("Inappropriate I/O control operation") when an ioctl isn't supported, while -EINVAL is used for invalid arguments. Support for termiox was added by commit `1d65b4a088` ("tty: Add termiox") in 2008 but no driver support ever followed and it was recently ripped out by commit `e0efb3168d` ("tty: Remove dead termiox code"). Fix the return value for the unsupported termiox ioctls, which have always returned -EINVAL, by explicitly returning -ENOTTY rather than removing them completely and falling back to the default unrecognised- ioctl handling.

README

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.
