Revert "HID: microsoft: fix invalid rdesc for 3k kbd"
This reverts commit 3ccc60f9d8c39180c205dba1a020735bda1b2491. While investigating bug https://bugzilla.kernel.org/show_bug.cgi?id=37982 , there was solid evidences that Microsoft reused the same report descriptor for the its Digital Media keyboard series. Since 1989dad "HID: input: ignore System Control application usages if not System Controls", the keyboard series do not produce a spurious joystick input device inode without needing to patch the problematic report descriptor. As such the MS_RDESC_3K reportdescriptor fixup can be removed. Signed-off-by: Michel Hermier <michel.hermier@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
