Title
Input: psxpad-spi - set driver data before use
Summary
In the Linux kernel, the following vulnerability has been resolved: Input: psxpad-spi - set driver data before use psxpad_spi_suspend() retrieves the controller state with spi_get_drvdata(), but probe never stores it, so suspend dereferences a NULL pointer. Store it during probe.
Severity
