The idle_state is not meant for host-only mode. When the device acts as a
host, it fails to exit the idle state once entered. This prevents new
USB gadgets from being detected once plugged in.
Commit 032ec49f53 ("usb: musb: drop useless board_mode usage") removed
a is_otg_enabled() check in the try_idle() that prevented from entering
idle_state. This was removed because at that time it was not possible to
select host-only mode with CONFIG_USB_MUSB_HOST so dual role was always
set.
Add #ifndef CONFIG_USB_MUSB_HOST around try_idle() callback to prevent
from entering idle_state when host-only mode has been selected.

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.
