2014-10-20platform: x86: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-06-10ix86/mid/thermal: Introduce the use of the managed version of kzallocHimangi Saraogi
This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2013-09-05platform: x86: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2013-01-03Drivers: platform: x86: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-07-24Thermal: Make Thermal trip points writeableDurgadoss R
Some of the thermal drivers using the Generic Thermal Framework require (all/some) trip points to be writeable. This patch makes the trip point temperatures writeable on a per-trip point basis, and modifies the required function call in thermal.c. This patch also updates the Documentation to reflect the new change.

2012-03-20platform-x86: intel_mid_thermal: turn off thermistor voltage by defaultMika Westerberg
