Description
In the Linux kernel, the following vulnerability has been resolved:

EDAC/altera: Drop __init from ECC setup paths for re-probe safety

Sashiko reports:

"Does suppressing sysfs unbinding fully prevent the execution of freed __init
memory? If altr_sysmgr_regmap_lookup_by_phandle() returns -EPROBE_DEFER, the
probe is deferred until after __init memory is freed."

The a10 EDAC .setup callbacks (sdmmc, ethernet, nand, dma, usb, qspi) and
their helpers (altr_init_a10_ecc_device_type, altr_init_a10_ecc_block) were
marked __init. These run from the probe path, which may execute after init
memory is freed -- e.g. a probe deferred via -EPROBE_DEFER that only succeeds
once a late/module dependency appears, or a manual unbind/rebind. Calling
__init code then dereferences freed memory. Remove __init so these functions
remain valid at runtime.
