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.
