This mechanism needs a\nstruct device to work so fwnode-based lookup with no device associated\ncurrently causes a NULL-pointer deference.\n\nAdding this functionality will require a larger rework and it has never\nworked anyway so add a check that allows the kernel to gracefully handle\nthis situation with an error ahead of implementing that functionality as\na new feature.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/7f9eb6aaf9a3ab7fa2b7dcc38660c27db12d4ec1","tags":[]},{"url":"https://git.kernel.org/stable/c/cf73c3fc03c43a8a86fd487c62390b4744eff9ec","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
