The relevant history introducing serial_lsr_in() looks as follows: $ git log --graph --oneline --boundary 9fafe733514b..df36f3e3fbb7 -- drivers/tty/serial/8250/8250_port.c *df36f3e3fbMerge tag 'v5.19-rc3' into tty-next |\ | *be03b0651fserial: 8250: Store to lsr_save_flags after lsr read * | ... * |bdb70c424dserial: 8250: Create serial_lsr_in() * |ce338e4477serial: 8250: Store to lsr_save_flags after lsr read * | ... |/ o9fafe73351tty: remove CMSPAR ifdefs So the patch "serial: 8250: Store to lsr_save_flags after lsr read" was introduced twice and in one branch it was followed up by commitbdb70c424d("serial: 8250: Create serial_lsr_in()") which moved explicit lsr_saved_flags handling into a new function serial_lsr_in(). When the two branches were merged in commitdf36f3e3fb, we got both, serial_lsr_in() and the explicit lsr_saved_flags handling. So drop the explicit lsr_saved_flags handling.

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.
