Log message:
Our ACPI namerefs are pointers to the byte structures for ACPI names.
These are not in a printable format, hence printing them as string is
wrong. Additionally, aml_searchrel()/aml_searchname() expect the name
to be passed in a printable format as well. Passing a nameref can lead
to an out-of-bounds read, and the comparison can fail. Hence make sure
that namerefs are passed to aml_getname() first, which returns printable
strings. Note that aml_getname() uses a static buffer, so there are a
few restrictions how the string can be used.
