Clang warns: drivers/input/mousedev.c:653:63: error: implicit conversion from 'int' to 'signed char' changes value from 200 to -56 [-Wconstant-conversion] client->ps2[1] = 0x60; client->ps2[2] = 3; client->ps2[3] = 200; ~ ^~~ As far as I can tell, from http://www.computer-engineering.org/ps2mouse/ Under "Command Set" > "0xE9 (Status Request)" the value 200 is a valid sample rate. Using unsigned char, rather than signed char, for client->ps2 silences this warning.
