ACPICA: Fix exception code class checks
mainline inclusion from mainline-v5.12-rc1 commit 3dfaea3811f8b6a89a347e8da9ab862cdf3e30fe category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5LBE7 CVE: NA -------------------------------- ACPICA commit 1a3a549286ea9db07d7ec700e7a70dd8bcc4354e The macros to classify different AML exception codes are broken. For instance, ACPI_ENV_EXCEPTION(Status) will always evaluate to zero due to #define AE_CODE_ENVIRONMENTAL 0x0000 #define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL) Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero value for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES, as well as AE_CODE_AML, and not just AE_CODE_AML as the name suggests. This commit fixes those checks.
