[PATCH] input: tablet: pegasus_notetaker: USB PM fixes

Show all headers | View raw

In close() we only need usb_autopm_put_interface(), in reset_resume()
we need to set the device mode, and in suspend(), we must cancel
the workqueue's work.

Thanks Oliver for these changes. For me, everything works as before.

Dmitry, do you want a new version of the whole thing instead of this
fix?

thanks
