From fc522f3bdf43efa75b54775978b6b6c19d0d997d Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Thu, 11 May 2023 11:52:42 -0700 Subject: Input: libps2 - remove special handling of ACK for command byte When getting unexpected data while waiting for an acknowledgement it does not matter what command phase is currently executed, and ps2_handle_ack() should indicate that no further processing is needed for the received data byte. Remove PS2_FLAG_ACK_CMD and associated handling. Note that while it is possible to make ps2_handle_ack (and ps2_handle_repsonse) return void, it will be done when the code will be converted to common PS/2 interrupt handler later.
