If altr_sysmgr_regmap_lookup_by_phandle() returns -EPROBE_DEFER, the\nprobe is deferred until after __init memory is freed.\"\n\nThe a10 EDAC .setup callbacks (sdmmc, ethernet, nand, dma, usb, qspi) and\ntheir helpers (altr_init_a10_ecc_device_type, altr_init_a10_ecc_block) were\nmarked __init. These run from the probe path, which may execute after init\nmemory is freed -- e.g. a probe deferred via -EPROBE_DEFER that only succeeds\nonce a late/module dependency appears, or a manual unbind/rebind. Calling\n__init code then dereferences freed memory. Remove __init so these functions\nremain valid at runtime.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/4ec26cb7984740941892ad21fa974963c198bfaa","tags":[]},{"url":"https://git.kernel.org/stable/c/9846b85c2eb8b749c3f14bdcc31b1070f6aabba8","tags":[]},{"url":"https://git.kernel.org/stable/c/b62a264163ca51bee04785c581344751812395df","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
