[PATCH] input: Fix interrupt enable in i8042_ctr when enabling interrupt fails
...n the error path:
static int i8042_enable_kbd_port(void)
{
i8042_ctr &= ~I8042_CTR_KBDDIS;
i8042_ctr |= I8042_CTR_KBDINT;
if (i8042_command(&i8042_ctr, I8042_CMD_CTL_WCTR)) {
printk(KERN_ERR "i8042.c: Failed to enable KBD port.\n");
return -EIO;
}
return 0;
}
Same for i8042_enable_aux_port().
This leads to the question whether there are later writes of i8042_ctr
(possibly with other bits altered) to the hardware, which could
accidentally retry enabling interrupts.
I believe this possible, but unlikely (perhaps not so unlikely on
virtual machines). Scenarios involve enable succeedi...
