Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: xilinx: formatter_pcm: pass aud_drv_data to irq handlers
The irq handlers take a struct device pointer and call
dev_get_drvdata() to obtain the driver data. However, the driver
data is only set at the end of probe, after devm_request_irq(),
so an interrupt taken in between causes the handlers to pass a
NULL pointer to readl() and crash.
Pass the private data directly as the devm_request_irq() argument
instead of the device pointer, matching what the handlers expect.
