Then the probe fails without\ndisabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL.\n\nRather fix the error path: disable all the low level hardware in the\nerror path, by using the \"hsotg->ll_hw_enabled\" flag. Checking dr_mode\nhas been introduced to avoid a dual call to dwc2_lowlevel_hw_disable().\n\"ll_hw_enabled\" should achieve the same (and is used currently in the\nremove() routine).", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "33a06f1300a79cfd461cea0268f05e969d4f34ec", "status": "affected", "versionType": "git", "lessThan": "1f01027c51eb16145e8e07fafea3ca07ef102d06" }, { "version": "33a06f1300a79cfd461cea0268f05e969d4f34ec", "status": "affected", "versionType": "git", "lessThan": "cba76e1fb896b573f09f51aa299223276a77bc90" }, { "version": "33a06f1300a79cfd461cea0268f05e969d4f34ec", "status": "affected", "versionType": "git", "lessThan": "ffb8ab6f87bd28d700ab5c20d9d3a7e75067630d" }, { "version": "33a06f1300a79cfd461cea0268f05e969d4f34ec", "status": "affected", "versionType": "git", "lessThan": "6485fc381b6528b6f547ee1ff10bdbcbe31a6e4c" }, { "version": "33a06f1300a79cfd461cea0268f05e969d4f34ec", "status": "affected", "versionType": "git", "lessThan": "f747313249b74f323ddf841a9c8db14d989f296a" }, { "version": "c95e1f67b9a84479d1a6d2e9b123a1553af2a75e", "status": "affected", "versionType": "git" }, { "version": "7d2a4749e1589295c69183f7d79d5b62664b34d6", "status": "affected", "versionType": "git" }, { "version": "8a8841b9f3eb1f46e3fc6d56a9b9299c53f4f86f", "status": "affected", "versionType": "git" }, { "version": "fa7fd9ba18533e9aa5f718a06de3deb522a4b587", "status": "affected", "versionType": "git" }, { "version": "b2c2b88b049684b89776036f9a03fcc2d1bb3c22", "status": "affected", "versionType": "git" }, { "version": "e7c4b79d70a70b4b7b0a04c640238a2ef0a7a8c8", "status": "affected", "versionType": "git" }, { "version": "88dcd13872b11bd60e6d4cb6317821e1d367e524", "status": "affected", "versionType": "git" }, { "version": "4.4.233", "status": "affected", "versionType": "semver", "lessThan": "4.5" }, { "version": "4.9.233", "status": "affected", "versionType": "semver", "lessThan": "4.10" }, { "version": "4.14.194", "status": "affected", "versionType": "semver", "lessThan": "4.15" }, { "version": "4.19.140", "status": "affected", "versionType": "semver", "lessThan": "4.20" }, { "version": "5.4.59", "status": "affected", "versionType": "semver", "lessThan": "5.5" }, { "version": "5.7.16", "status": "affected", "versionType": "semver", "lessThan": "5.8" }, { "version": "5.8.2", "status": "affected", "versionType": "semver", "lessThan": "5.9" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "5.9", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "5.9" }, { "version": "5.10.177", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.105", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.22", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.2.9", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.2.*" }, { "version": "6.3", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
