Update\nsmc_ib_gid_check() to call smcr_port_err() after releasing the lock.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/00a59600ae72d24859d0ad1783a78bc921bc2599","tags":[]},{"url":"https://git.kernel.org/stable/c/0edcc4284392b28826b5d37532b366b291e6e0fa","tags":[]},{"url":"https://git.kernel.org/stable/c/34bcf11cd2528ae00bb6d764d808083c66824277","tags":[]},{"url":"https://git.kernel.org/stable/c/3d35f069e1c119992000d51236dbe54da2d4e61e","tags":[]},{"url":"https://git.kernel.org/stable/c/3d65a2eb4449fc9658fb860dea893025d028d90e","tags":[]},{"url":"https://git.kernel.org/stable/c/61cb282fe97b3b0ba32ca09417a693162bf4ae3f","tags":[]},{"url":"https://git.kernel.org/stable/c/a9b968e42690d784c241a0761c10253271f7df5d","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
