In 3.7, 8250 was unintentionally renamed to 8250_core. This happened in the commit835d844d1a(8250_pnp: do pnp probe before legacy probe). This made 8250.<xxxx> module options effectively defunct. Instead, 8250_core.<xxxx> worked. In 3.9, the commitf2b8dfd9e4(serial: 8250: Keep 8250.<xxxx> module options functional after driver rename) made the original options work again by introducing a hack. Later in 3.9, the commit9196d8acd7(TTY: 8250, revert module name change) changed the module name back to 8250 (from 8250_core). Since then, the hack was there to support the transient 8250_core.<xxxx> options. Those were present only in the 3.7..3.9 range. These transient options were deprecated by9326b047e4(TTY: 8250, deprecated 8250_core.* options) in v3.9 too. Now, after those 12 years, it is time to get rid of this hack completely.

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.
