Similar to controllers found Voxel, Delbin, Magpie and Bobba, the one found in Whitebox does not need to be reset after issuing power-on command, and skipping reset saves resume time.

The panel is connected with I2C and controls the bus, so the driver registers as an I2C slave device.

Notice that this seems to be a Duff device for performance[1]. So, although the code looks a bit _funny_, I didn't want to refactor or modify it beyond merely adding a fallthrough marking, which might be the least disruptive way to fix this issue.

The issue was originally discovered by Murray McAllister with this simple POC (if the following is executed by an unprivileged user it will instantly panic the system): int main(void) { int fd, ret; unsigned int buffer[10000]; fd = open("/dev/input/js0", O_RDONLY); if (fd == -1) printf("Error opening file\n"); ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer); printf("%d\n", ret); } The solution is to traverse internal buffer which is guaranteed to only contain valid date when constructing the map.
