From: Suniel Mahesh
Date: Tue Aug 02 2022 - 16:16:14 EST


This series does the following:

patch 1/2 extends functionality for GET_REPORT.

The current kernel implementation for GET_REPORT is that the kernel
sends back a zero filled report (of length == report_length), when
the Host request's a particular report from the device/gadget.

This changeset extends functionality for GET_REPORT by sending a
particular report based on report type and report number.

patch 2/2 adds a test application to test the extended
functionality.

please review and share your thoughts.
