Currently a clock reference is taken whenever the ->ndo_open callback for the modem netdev is called. That reference is dropped when the device is closed, in ipa_stop(). We no longer need this, because ipa_start_xmit() now handles the situation where the hardware power state is not active. Drop the clock reference in ipa_open() when we're done, and take a new reference in ipa_stop() before we begin closing the interface. Finally (and unrelated, but trivial), change the return type of ipa_start_xmit() to be netdev_tx_t instead of int. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

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.
