The patch titled
acpi_os_wait_semaphore(): don't complain about timeout
has been removed from the -mm tree. Its filename is
acpi_os_wait_semaphore-dont-complain-about-timeout.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to time out
and return True without acquiring the semaphore. There's no indication in
the spec that this is an actual error, so this message should be
debug-only, as the message for successful acquisition is.
This used to be an ACPI_DEBUG_PRINT, but it was mis-classified as
ACPI_DB_ERROR rather than ACPI_DB_MUTEX, so it got swept up in Thomas'
recent patch to enable ACPI error messages even without CONFIG_ACPI_DEBUG.
