Vulnerability from gsd

Details
In the Linux kernel, the following vulnerability has been resolved:
spi: cadence-qspi: fix pointer reference in runtime PM hooks
dev_get_drvdata() gets used to acquire the pointer to cqspi and the SPI
controller. Neither embed the other; this lead to memory corruption.
On a given platform (Mobileye EyeQ5) the memory corruption is hidden
inside cqspi->f_pdata. Also, this uninitialised memory is used as a
mutex (ctlr->bus_lock_mutex) by spi_controller_suspend().
