[PATCH 1/3] ACPI: improve function documentation for acpi_parse_entries_array()

From: Al Stone
Date: Tue Apr 03 2018 - 20:43:36 EST


I found the description of the table_size argument to the function
acpi_parse_entries_array() unclear and ambiguous. This is a minor
documentation change to improve that description so I don't misuse
the argument again in the future, and it is hopefully clearer to
other future users.
