[PATCH v1 1/1] gpiolib: Show more info for interrupt only lines in debugfs

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

Show more info for interrupt only lines in debugfs. It's useful
to monitor the lines that have been never requested as GPIOs,
but IRQs.

For the reference. May be applied together with

as a precursor.
