linux.git/drivers/acpi, branch v2.6.39 Linux kernel source tree ACPI / PM: Avoid infinite recurrence while registering power resources 2011-04-26T09:33:18+00:00 Rafael J. Wysocki rjw@sisk.pl 2011-04-26T09:33:18+00:00 7bed50c5edf5cba8dd515a31191cbfb6065ddc85 There is at least one BIOS with a DSDT containing a power resource object with a _PR0 entry pointing back to that power resource. In consequence, while registering that power resource acpi_bus_get_power_flags() sees that it depends on itself and tries to register it again, which leads to an infinitely deep recurrence. This problem was introduced by commit bf325f9538d8c89312be305b9779e (ACPI / PM: Register power resource devices as soon as they are needed). To fix this problem use the observation that power resources cannot be power manageable and prevent acpi_bus_get_power_flags() from being called for power resource objects.

acpi: Remove sysfs_create_link from video driver 2011-03-28T20:05:29+00:00 Matthew Garrett mjg@redhat.com 2011-03-28T12:46:02+00:00 445aef374594207b278477dfd98fc5d1498d353a The acpi video driver attempts to explicitly create a sysfs link between the acpi device and the associated PCI device. However, we're now also doing this from the backlight core, which means that we get a backtrace caused by a duplicate file. Remove the code and leave it up to the backlight core.
