commit eeb8c19896952e18fb538ec76e603884070a6c6a upstream.

This reverts commit bad3fa2fb9206f4dcec6ddef094ec2fbf6e8dcb2.

Commit bad3fa2fb920 ("ACPI: Suppress misleading SPCR console message
when SPCR table is absent") mistakenly assumes acpi_parse_spcr()
returning 0 to indicate a failure to parse SPCR. While addressing the
resultant incorrect logging it was deemed that dropping the message is
a better approach as it is not particularly useful.

Roll back the commit introducing the bug as a step towards dropping
the log message.
