Title
accel/ethosu: check MMIO mapping errors in probe
Summary
In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: check MMIO mapping errors in probe devm_platform_ioremap_resource() returns an error pointer when the register resource cannot be mapped. ethosu_probe() stores it and continues until initialization dereferences it through MMIO accessors. Return the mapping error before initializing the device.
