With gcc 4.1.2:
drivers/tty/serial/qcom_geni_serial.c: In function ‘qcom_geni_serial_probe’:
drivers/tty/serial/qcom_geni_serial.c:1261: warning: ‘drv’ may be used uninitialized in this function
Indeed, if dev.of_node is NULL, drv will be used uninitialized, and
dereferenced in uart_add_one_port(). However, as this driver supports
DT only, dev.of_node will always be valid.
Hence remove the useless check for dev.of_node, killing the warning as a
side effect.
Fixes: 8a8a66a1a1 ("tty: serial: qcom_geni_serial: Add support for flow control")

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
