[ Upstream commit125459e19e] Fix bug in nt35560_set_brightness() which causes the function to erroneously report an error. mipi_dsi_dcs_write() returns either a negative value when an error occurred or a positive number of bytes written when no error occurred. The buggy code reports an error under either condition.

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.
