zhong jiang 547fc22875 usb: typec: fusb302: Fix an undefined reference to 'extcon_get_state'
Fixes the following compile error:

drivers/usb/typec/tcpm/fusb302.o: In function `tcpm_get_current_limit':
fusb302.c:(.text+0x3ee): undefined reference to `extcon_get_state'
fusb302.c:(.text+0x422): undefined reference to `extcon_get_state'
fusb302.c:(.text+0x450): undefined reference to `extcon_get_state'
fusb302.c:(.text+0x48c): undefined reference to `extcon_get_state'
drivers/usb/typec/tcpm/fusb302.o: In function `fusb302_probe':
fusb302.c:(.text+0x980): undefined reference to `extcon_get_extcon_dev'
make: *** [vmlinux] Error 1

It is because EXTCON is build as a module, but FUSB302 is not.

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.
