* | | pata_pdc2027x: add Power Management supportBartlomiej Zolnierkiewicz2011-10-141-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes IDE -> libata regression. There shouldn't be any problems with it as corresponding IDE's host driver (pdc202xx_new) has been supporting PCI Power Management since Oct 10 2008 (commit feb22b7f "ide: add proper PCI PM support (v2)") and IDE PM since Jun 14 2003 (patch v2.5.73 "ide: Power Management").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mirrors a very old commit (3160d5416f39da9d9, "sis5513: add ->udma_filter method for chipset_family >= ATA_133") to the old sis5513 IDE driver that prevents certain setups from working. UDMA6 (ATA/133) is not supported on some chipsets and we need to ensure this mode is not chosen even if a connected drive supports it. Port this old patch forward to the new PATA driver to ensure UDMA5 is the highest mode used if that is what is supported. Kernel bugzilla #41582.

The only effect is to print a debugging message including ap->print_id. The code is rewritten to not call sata_dwc_port_stop, but instead to jump to a local label that prints the original error message and the print_id information. In the case where hsdevp has been already allocated (but not yet stored in ap), this value is freed as well.

* | [libata] sata_sil: fix used-uninit warningJeff Garzik2011-08-181-1/+1
|/ | | | | | | | | | | | | | Init 'serror' to silence the following warning: drivers/ata/sata_sil.c: In function ‘sil_interrupt’: drivers/ata/sata_sil.c:453:14: warning: ‘serror’ may be used uninitialized in this function [-Wuninitialized] This is not a 'can never happen' but is nonetheless extremely unlikely. The easiest and cleanest warning fix is simply to init the var, rather than worry about marking the var uninit-ok. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| * ACPI: constify ops structsVasiliy Kulikov2011-07-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Structs battery_file, acpi_dock_ops, file_operations, thermal_cooling_device_ops, thermal_zone_device_ops, kernel_param_ops are not changed in runtime. It is safe to make them const. register_hotplug_dock_device() was altered to take const "ops" argument to respect acpi_dock_ops' const notion.
