The goal of this series is to report the firmware version of ETAS
ES58x devices through ethtool.
The easiest way to do so is by using usb_cache_string so that we do
not have to manage errors.
First patch exports usb_cache_string(). The second patch then does a
small cleanup in the existing function and replace existing code with
usb_cache_string(). The third and final patch reports the firmware
version of the device to the userland through ethtool.
* Changelog *
v1 -> v2:
* was a single patch. It is now a series of three patches.
* add a first new patch to export usb_cache_string().
* add a second new patch to apply usb_cache_string() to existing code.
* add missing check on product info string to prevent a buffer overflow.
* add comma on the last entry of struct es58x_parameters.
