Hi All: drivers/spi/spi.c:
The function to_spi_device() could return NULL, but some callers in this file does not check the return value while directly dereference it, which seems potentially unsafe. Such callers include spidev_release(), spi_dev_check(), driver_override_store(), etc. -- Kind Regards, Yizhuo Zhai Computer Science, Graduate Student University of California, Riverside
