Hi Eugen: In function isc_interrupt(), variable "isc_intsr" and "isc_intmask" (drivers/media/platform/atmel/atmel-isc-base.c) could be uninitialized if regmap_read() fails and return -EINVAL . However, they are used to decide the control flow later in the if statement, which is potentially unsafe.
We cannot simply return -EINVAL in isc_interrupt() because it is out of the return type: irqreturn_t. Thanks for your time to check this case. -- Kind Regards, Yizhuo Zhai Computer Science, Graduate Student University of California, Riverside
