This patch introduces a specific test case for the EVIOCGKEY ioctl. The test covers the case where len > maxlen in the EVIOCGKEY(sizeof(keystate)), keystate) ioctl. Signed-off-by: Dana Elfassy <dangel101@xxxxxxxxx> --- Changes in v3: - Edited commit's subject and description - Renamed variable rep_values to keystate - Added argument to selftest_uinput_create_device() - Removed memset Changes in v2: - Added following note about the patch's dependency This patch depends on '[v3] selftests/input: Introduce basic tests for evdev ioctls' [1] sent to the ML.
