2010-04-26hwmon: (sht15) Properly handle the case CONFIG_REGULATOR=nJean Delvare
commit c7a78d2c2e2537fd24903e966f34aae50319d587 upstream. When CONFIG_REGULATOR isn't set, regulator_get_voltage() returns 0. Properly handle this case by not trusting the value.

2010-04-26hwmon: (sht15) Fix sht15_calc_temp interpolation functionJerome Oufella
commit 328a2c22abd08911e37fa66f1358f829cecd72e9 upstream. I discovered two issues. First the previous sht15_calc_temp() loop did not iterate through the temppoints array since the (data->supply_uV > temppoints[i - 1].vdd) test is always true in this direction. Also the two-points linear interpolation function was returning biased values due to a stray division by 1000 which shouldn't be there. [JD: Also change the default value for d1 from 0 to something saner.] Signed-off-by: Jerome Oufella <jerome.oufella@savoirfairelinux.com> Acked-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-04-26lis3: fix show rate for 8 bits chipsÉric Piel
commit 4b5d95b3809bcd77599122494aa3f575cd6ab1b9 upstream. Originally the driver was only targeted to 12bits sensors. When support for 8bits sensors was added, some slight difference in the registers were overlooked. This should fix it, both for initialization, and for displaying the rate.

commit 4d7a5644e4adfafe76c2bd8ee168e3f3b5dae3a8 upstream. Add missing newline to dev_warn() message string.

commit 8d59582a867470a3e0c3eced4a01625ae8dc546b upstream. An off-by-one error caused some inputs to not be created by the driver when they should.

2010-03-15macintosh/hwmon/ams: Fix device removal sequenceJean Delvare
commit 98ceb75c7c14eada76b0aa9f03a635a735cee3cb upstream. Some code that is in ams_exit() (the module exit code) should instead be called when the device (not module) is removed. It probably doesn't make much of a difference in the PMU case, but in the I2C case it does matter. I make no guarantee that my fix isn't racy, I'm not familiar enough with the ams driver code to tell for sure.

2010-02-23hwmon: (adt7462) Wrong ADT7462_VOLT_COUNTRay Copeland
commit 85f8d3e5faea8bd36c3e5196f8334f7db45e19b2 upstream. The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the for loops that use this as a limit count are of the typical form, "for (n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages w/o missing the last one it is necessary for the count to be one greater than it is. (Specifically, you will miss the +1.5V 3GPIO input with count = 12 vs. 13.) Signed-off-by: Ray Copeland <ray.copeland@aprius.com> Acked-by: "Darrick J.

2010-02-23hwmon: (lm78) Request I/O ports individually for probingJean Delvare
commit 197027e6ef830d60e10f76efc8d12bf3b6c35db5 upstream. Different motherboards have different PNP declarations for LM78/LM79 chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have an LM78 or LM79 chip, the useful port range will be requested again, as a single block. This fixes the driver on the Olivetti M3000 DT 540, at least.

There is no point in implementing a detect callback for the LTC4215 and LTC4245, as these devices can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same.

2009-09-23spi: prefix modalias with "spi:"Anton Vorontsov
This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

2009-09-23dme1737: Keep index within pwm_config[]Roel Kluin
The static code scanner "Parfait" reported this because pwm_config is only 3 bytes - pwm_config[3] is out of range. Since this code path is never called with ix == 3 (the device has no PWM4 output) this doesn't change anything in practice. But to encourage testing with Parfait, lets make the warning go away...

2009-09-22hwmon: applesmc: restore accelerometer and keyboard backlight on resumeHenrik Rydberg
On resume from suspend, the driver currently resets the logical state as if it was brought up from halt. This patch uses the dev_pm_ops.resume/restore methods to synchronize the hardware with the memorized logical state, in effect bringing back the accelerometer and backlight to the state prior to suspend. Works for both suspend to ram and hibernation. The patch has zero effect on the running state.

2009-09-22drivers/hwmon/adm1021.c: add low_power support for adm1021 driverMichael Abbott
Occasionally it is helpful to be able to turn a temperature sensor off (for example if it's making unwanted electrical noise). This patch adds a sysfs node to put any adm1021 compatible device into low power mode.

2009-09-22drivers/hwmon/adm1021.c: support high precision ADM1023 remote sensorMichael Abbott
The ADM1023 temperature sensor supports higher resolution for its external sensor (sensitivity of 1/8 deg C). This patch makes this higher resolution available through the appropriate temperature sysfs nodes. Curiously, this functionality was available in the 2.4 kernel driver (but formatted in a less helpful manner).
