So this results in an spi controller with an unbound parent\nand unmapped register space (because devm_ioremap_resource() is undone).\nSo using the remaining spi controller probably results in an oops.\n\nInstead unregister the controller unconditionally and only skip hardware\naccess and clk disable.\n\nAlso add a warning about resume failing and return zero unconditionally.\nThe latter has the only effect to suppress a less helpful error message by\nthe spi core.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/618770d4d8e40b7f8ed9eb5f210cd9164dfac47d","https://git.kernel.org/stable/c/77806d7c9bebe40a8cdce2b8d30fbe6511745df8","https://git.kernel.org/stable/c/9448bc1dee65f86c0fe64d9dea8b410af0586886","https://git.kernel.org/stable/c/f6974fb20499e3b6522daa7aec822aac11dfcf42"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2023-53758","score":0.00186,"percentile":0.08199,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
