From: Suzuki K Poulose <suzuki.poulose@arm.com> mainline inclusion from mainline-v5.0-rc1 commit a3dcea2c85129716f323d504b087a04200687242 category: bugfix bugzilla: 46773 CVE: NA References: https://gitee.com/src-openeuler/kernel/issues/I235Y8 --------------------------- Remove duplicate entries for Qualcomm erratum 1003. Since the entries are not purely based on generic MIDR checks, use the multi_cap_entry type to merge the entries.
