commit55a9968c7eupstream. The commit15add06841("gpio: pca953x: add ->set_config implementation") introduced support for bias setting. However this, due to being half-baked, brought potential issues: - the turning bias via disabling makes the pin floating for a while; - once enabled, bias can't be disabled. Fix all these by adding support for bias disabling and move the disabling part under the corresponding conditional. While at it, add support for default setting, since it's cheap to add.

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.
