drivers: thermal: tsens: Don't print error message on -EPROBE_DEFER

2019-06-15T09:52:53Z

[ Upstream commit fc7d18cf6a923cde7f5e7ba2c1105bb106d3e29a ] We print a calibration failure message on -EPROBE_DEFER from nvmem/qfprom as follows: [ 3.003090] qcom-tsens 4a9000.thermal-sensor: version: 1.4 [ 3.005376] qcom-tsens 4a9000.thermal-sensor: tsens calibration failed [ 3.113248] qcom-tsens 4a9000.thermal-sensor: version: 1.4 This confuses people when, in fact, calibration succeeds later when nvmem/qfprom device is available. Don't print this message on a -EPROBE_DEFER. Signed-off-by: Amit Kucheria Signed-off-by: Eduardo Valentin Signed-off-by: Sasha Levin

thermal: rcar_gen3_thermal: disable interrupt in .remove

2019-06-15T09:52:53Z

[ Upstream commit 63f55fcea50c25ae5ad45af92d08dae3b84534c2 ] Currently IRQ remains enabled after .remove, later if device is probed, IRQ is requested before .thermal_init, this may cause IRQ function be called before device is initialized. this patch disables interrupt in .remove, to ensure irq function only be called after device is fully initialized.

thermal/intel_powerclamp: fix truncated kthread name

2019-03-18T14:26:33Z

kthread name only allows 15 characters (TASK_COMMON_LEN is 16). Thus rename the kthreads created by intel_powerclamp driver from "kidle_inject/ + decimal cpuid" to "kidle_inj/ + decimal cpuid" to avoid truncated kthead name for cpu 100 and later. Signed-off-by: Zhang Rui

thermal: mtk: Allocate enough space for mtk_thermal.

2019-03-18T14:23:10Z

The mtk_thermal struct contains a 'struct mtk_thermal_bank banks[];', but the allocation only allocates sizeof(struct mtk_thermal) bytes, which cause out of bound access with the ->banks[] member. Change it to a fixed size array instead. Signed-off-by: Pi-Hsun Shih Reviewed-by: Daniel Lezcano Signed-off-by: Zhang Rui

thermal/int340x_thermal: fix mode setting

2019-03-18T14:13:21Z

int3400 only pushes the UUID into the firmware when the mode is flipped to "enable". The current code only exposes the mode flag if the firmware supports the PASSIVE_1 UUID, which not all machines do. Remove the restriction. Signed-off-by: Matthew Garrett Signed-off-by: Zhang Rui

thermal/int340x_thermal: Add additional UUIDs

2019-03-18T14:13:21Z

Add more supported DPTF policies than the driver currently exposes. Signed-off-by: Matthew Garrett Cc: Nisha Aram Signed-off-by: Zhang Rui

thermal: bcm2835: Fix crash in bcm2835_thermal_debugfs

2019-03-18T14:11:06Z

"cat /sys/kernel/debug/bcm2835_thermal/regset" causes a NULL pointer dereference in bcm2835_thermal_debugfs. The driver makes use of the implementation details of the thermal framework to retrieve a pointer to its private data from a struct thermal_zone_device, and gets it wrong - leading to the crash. Instead, store its private data as the drvdata and retrieve the thermal_zone_device pointer from it.
