[PATCH] acpi: apei: fix the wrongly parse generic error status block

Show all headers | View raw

The revision 0x300 generic error data entry is different with the old
version. when ghes_do_proc traverses to get the data entry, it does not
consider this difference. so when error status block has revision 0x300
data entry, it will have issue.
