hwmon: (sht15) Fix integer overflow in humidity calculation

2011-03-23T20:04:16Z

commit ccd32e735de7a941906e093f8dca924bb05c5794 upstream. An integer overflow occurs in the calculation of RHlinear when the relative humidity is greater than around 30%. The consequence is a subtle (but noticeable) error in the resulting humidity measurement.

mmc: sdio: remember new card RCA when redetecting card

2011-03-23T20:04:12Z

commit 0aab3995485b8a994bf29a995a008c9ea4a28054 upstream. During redetection of a SDIO card, a request for a new card RCA was submitted to the card, but was then overwritten by the old RCA. This caused the card to be deselected instead of selected when using the incorrect RCA. This bug's been present since the "oldcard" handling was introduced in 2.6.32.

HID: Do not create input devices for feature reports

2011-03-23T20:04:09Z

commit f635bd11c8d332d917fb9a4cad3071b2357d5b2a upstream. When the multi input quirk is set, there is a new input device created for every feature report. Since the idea is to present features per hid device, not per input device, revert back to the original report loop and change the feature_mapping() callback to not take the input device as argument.

HID: ACRUX - activate the device immediately after binding

2011-03-23T20:04:09Z

commit 0ae43810976bc969ee158510c4acbe70ed136e61 upstream. This device does not tolerate delayed opening and goes into a coma if we try to that. Ubuntu even has a crutch for udev that opened the device upon seeing it for the first time, but it did not work if we happened to boot with the device attached, since by the time userspace got around opening the device it was too late. Let's start the device immediately to deal with this issue. Reported-by: Sergei Kolzun Signed-off-by: Dmitry Torokhov Signed-off-by: Jiri Kosina Signed-off-by: Greg Kroah-Hartman

commit ed0f36bc5719b25659b637f80ceea85494b84502 upstream. The use of blk_execute_rq_nowait() implies __blk_put_request() is needed in stpg_endio() rather than blk_put_request() -- blk_finish_request() is called with queue lock already held.

PCI: sysfs: Fix failure path for addition of "vpd" attribute

2011-03-23T20:03:59Z

commit 0f12a4e29368a9476076515881d9ef4e5876c6e2 upstream. Commit 280c73d ("PCI: centralize the capabilities code in pci-sysfs.c") changed the initialisation of the "rom" and "vpd" attributes, and made the failure path for the "vpd" attribute incorrect. We must free the new attribute structure (attr), but instead we currently free dev->vpd->attr. That will normally be NULL, resulting in a memory leak, but it might be a stale pointer, resulting in a double-free. Found by inspection; compile-tested only.

PCI: do not create quirk I/O regions below PCIBIOS_MIN_IO for ICH

2011-03-23T20:03:58Z

commit 87e3dc3855430bd254370afc79f2ed92250f5b7c upstream. Some broken BIOSes on ICH4 chipset report an ACPI region which is in conflict with legacy IDE ports when ACPI is disabled. Even though the regions overlap, IDE ports are working correctly (we cannot find out the decoding rules on chipsets). So the only problem is the reported region itself, if we don't reserve the region in the quirk everything works as expected. This patch avoids reserving any quirk regions below PCIBIOS_MIN_IO which is 0x1000. Some regions might be (and are by a fast google query) below this border, but the only difference is that they won't be reserved anymore. They should still work though the same as before. The conflicts look like (1f.0 is bridge, 1f.1 is IDE ctrl): pci 0000:00:1f.1: address space collision: [io 0x0170-0x0177] conflicts with 0000:00:1f.0 [io 0x0100-0x017f] At 0x0100 a 128 bytes long ACPI region is reported in the quirk for ICH4. ata_piix then fails to find disks because the IDE legacy ports are zeroed: ata_piix 0000:00:1f.1: device not available (can't reserve [io 0x0000-0x0007]) References: https://bugzilla.novell.com/show_bug.cgi?id=558740 Signed-off-by: Jiri Slaby Cc: Bjorn Helgaas Cc: "David S.
