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. An explicit cast silences this
warning.
