power_supply_sysfs.c accept wrrites of strings to "usb_type" for strings values matching an entry in POWER_SUPPLY_USB_TYPE_TEXT[]. If such a string value is written then the int value passed to ucs1002_set_property() will be an enum power_supply_usb_type value. Before this change ucs1002_set_usb_type() expected the value to be an index into ucs1002_usb_types[]. Adjust ucs1002_set_usb_type() to use the enum value directly so that writing string values works. The list of supported types in ucs1002_usb_types[] is: PD, SDP, DCP, CDP. The [POWER_SUPPLY_USB_TYPE_]SDP, DCP and CDP enum labels have a value of 1, 2 and 3. So userspace selecting SDP, DCP or CDP by writing 1, 2 or 3 will keep working. POWER_SUPPLY_USB_TYPE_PD which is mapped to the ucs1002 dedicated mode however has a value of 6. Before this change writing 0 would select the dedicated mode. To preserve userspace API compatibility also map POWER_SUPPLY_USB_TYPE_UNKNOWN (which is 0) to the dedicated mode.

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 reStructuredText 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.
