Subject[PATCH 6/6] acpi: Return -ENOENT in acpi_table_parse() and fix wrong comment.
Date
The comment about return value of acpi_table_parse() is incorrect.
This patch fix it.

Furthermore, if the table is not found, return 1 means nothing, and
make it difficult to write the comment. So return -ENOENT when the
table is not found, and correct the comment.
