Smatch warns:
drivers/media/i2c/ds90ub960.c:1671 ub960_rxport_add_serializer():
err: 'rxport->ser.client' dereferencing possible ERR_PTR()
i2c_new_client_device() returns error pointers on failure and in
dev_dbg statement we are dereferencing error pointer which is a bug.
Fix this by using IS_ERR() which checks for error pointers.
Fixes: afe267f2d3 ("media: i2c: add DS90UB960 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.
