The input core already filters out EV_KEY events for KEY_RESERVED, remove the check for this in tpacpi_input_send_key() and rely on the input core filtering instead. Also change tpacpi_input_send_key() to only report the scancode once instead of reporting it on both press and release. Together these 2 changes make tpacpi_input_send_key() behave the same as sparse_keymap_report_event(). The goal of this patch is to have a separate commit with the slightly different behavior from sparse_keymap_report_event() before switching over to using the sparse-keymap helpers.
