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":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/dwc2/platform.c"],"versions":[{"version":"33a06f1300a79cfd461cea0268f05e969d4f34ec","lessThan":"1f01027c51eb16145e8e07fafea3ca07ef102d06","status":"affected","versionType":"git"},{"version":"33a06f1300a79cfd461cea0268f05e969d4f34ec","lessThan":"cba76e1fb896b573f09f51aa299223276a77bc90","status":"affected","versionType":"git"},{"version":"33a06f1300a79cfd461cea0268f05e969d4f34ec","lessThan":"ffb8ab6f87bd28d700ab5c20d9d3a7e75067630d","status":"affected","versionType":"git"},{"version":"33a06f1300a79cfd461cea0268f05e969d4f34ec","lessThan":"6485fc381b6528b6f547ee1ff10bdbcbe31a6e4c","status":"affected","versionType":"git"},{"version":"33a06f1300a79cfd461cea0268f05e969d4f34ec","lessThan":"f747313249b74f323ddf841a9c8db14d989f296a","status":"affected","versionType":"git"},{"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"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/dwc2/platform.c"],"versions":[{"version":"5.9","status":"affected"},{"version":"0","lessThan":"5.9","status":"unaffected","versionType":"semver"},{"version":"5.10.177","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.105","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.22","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.2.9","lessThanOrEqual":"6.2.*","status":"unaffected","versionType":"semver"},{"version":"6.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.9","versionEndExcluding":"5.10.177"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.9","versionEndExcluding":"5.15.105"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.9","versionEndExcluding":"6.1.22"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.9","versionEndExcluding":"6.2.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.9","versionEndExcluding":"6.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4.233"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9.233"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.14.194"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19.140"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4.59"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.7.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/1f01027c51eb16145e8e07fafea3ca07ef102d06"},{"url":"https://git.kernel.org/stable/c/cba76e1fb896b573f09f51aa299223276a77bc90"},{"url":"https://git.kernel.org/stable/c/ffb8ab6f87bd28d700ab5c20d9d3a7e75067630d"},{"url":"https://git.kernel.org/stable/c/6485fc381b6528b6f547ee1ff10bdbcbe31a6e4c"},{"url":"https://git.kernel.org/stable/c/f747313249b74f323ddf841a9c8db14d989f296a"}],"title":"usb: dwc2: fix a devres leak in hw_enable upon suspend resume","x_generator":{"engine":"bippy-1.2.0"}}}}
