This breaks module loading on, e.g. a T23 with outdated BIOS, and the module will refuse to load unless the "force_load=1" parameter is given. Fix the quirk tables so that they can also match the outdated BIOSes, which in turn will both fix the module loading, and also warn the user that he is using outdated firmware and should upgrade. This fixes a serious regression, introduced by commit e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict when detecting a ThinkPad". http://bugzilla.kernel.org/show_bug.cgi?id=14597 Reported-by: Paul Kimoto Signed-off-by: Henrique de Moraes Holschuh Tested-by: Paul Kimoto Signed-off-by: Andrew Morton Signed-off-by: Len Brown --- drivers/platform/x86/thinkpad_acpi.c | 24 ++++++++++++++++++------ 1 file changed, 18 insertions(+), 6 deletions(-) (limited to 'drivers') diff --git a/drivers/platform/x86/thinkpad_acpi.c b/drivers/platform/x86/thinkpad_acpi.c index 03c0a56f0c8..a848c7e20ae 100644 --- a/drivers/platform/x86/thinkpad_acpi.c +++ b/drivers/platform/x86/thinkpad_acpi.c @@ -1680,36 +1680,48 @@ static void tpacpi_remove_driver_attributes(struct device_driver *drv) | (__bv1) << 8 | (__bv2) } #define TPV_Q_X(__v, __bid1, __bid2, __bv1, __bv2, \ - __eid1, __eid2, __ev1, __ev2) \ + __eid, __ev1, __ev2) \ { .vendor = (__v), \ .bios = TPID(__bid1, __bid2), \ - .ec = TPID(__eid1, __eid2), \ + .ec = __eid, \ .quirks = (__ev1) << 24 | (__ev2) << 16 \ | (__bv1) << 8 | (__bv2) } #define TPV_QI0(__id1, __id2, __bv1, __bv2) \ TPV_Q(PCI_VENDOR_ID_IBM, __id1, __id2, __bv1, __bv2) +/* Outdated IBM BIOSes often lack the EC id string */ #define TPV_QI1(__id1, __id2, __bv1, __bv2, __ev1, __ev2) \ TPV_Q_X(PCI_VENDOR_ID_IBM, __id1, __id2, \ - __bv1, __bv2, __id1, __id2, __ev1, __ev2) + __bv1, __bv2, TPID(__id1, __id2), \ + __ev1, __ev2), \ + TPV_Q_X(PCI_VENDOR_ID_IBM, __id1, __id2, \ + __bv1, __bv2, TPACPI_MATCH_UNKNOWN, \ + __ev1, __ev2) +/* Outdated IBM BIOSes often lack the EC id string */ #define TPV_QI2(__bid1, __bid2, __bv1, __bv2, \ __eid1, __eid2, __ev1, __ev2) \ TPV_Q_X(PCI_VENDOR_ID_IBM, __bid1, __bid2, \ - __bv1, __bv2, __eid1, __eid2, __ev1, __ev2) + __bv1, __bv2, TPID(__eid1, __eid2), \ + __ev1, __ev2), \ + TPV_Q_X(PCI_VENDOR_ID_IBM, __bid1, __bid2, \ + __bv1, __bv2, TPACPI_MATCH_UNKNOWN, \ + __ev1, __ev2) #define TPV_QL0(__id1, __id2, __bv1, __bv2) \ TPV_Q(PCI_VENDOR_ID_LENOVO, __id1, __id2, __bv1, __bv2) #define TPV_QL1(__id1, __id2, __bv1, __bv2, __ev1, __ev2) \ TPV_Q_X(PCI_VENDOR_ID_LENOVO, __id1, __id2, \ - __bv1, __bv2, __id1, __id2, __ev1, __ev2) + __bv1, __bv2, TPID(__id1, __id2), \ + __ev1, __ev2) #define TPV_QL2(__bid1, __bid2, __bv1, __bv2, \ __eid1, __eid2, __ev1, __ev2) \ TPV_Q_X(PCI_VENDOR_ID_LENOVO, __bid1, __bid2, \ - __bv1, __bv2, __eid1, __eid2, __ev1, __ev2) + __bv1, __bv2, TPID(__eid1, __eid2), \ + __ev1, __ev2) static const struct tpacpi_quirk tpacpi_bios_version_qtable[] __initconst = { /* Numeric models ------------------ */ -- cgit v1.2.3-70-g09d2 From 7005291706341a11c094f39a756a01c9e649e5f9 Mon Sep 17 00:00:00 2001 From: Peter Feuerer Date: Tue, 17 Nov 2009 14:07:21 -0800 Subject: acerhdf: return temperature in milidegree instead of degree Return temperature in milidegree instead of degree, as sysfs-api requires the temperature in milidegree.
