2020-12-11irqchip/ti-sci-inta: Fix printing of inta id on probe successLokesh Vutla
On a successful probe, the driver tries to print a success message with INTA device id. It uses pdev->id for printing the id but id is stored in inta->ti_sci_id. Fix it by correcting the dev_info parameter.

2020-12-11irqchip/gic, gic-v3: Make SGIs use handle_percpu_devid_irq()Valentin Schneider
handle_percpu_devid_fasteoi_ipi() states: * The biggest difference with the IRQ version is that the interrupt is * EOIed early, as the IPI could result in a context switch, and we need to * make sure the IPI can fire again All that can actually happen scheduler-wise within the handling of an IPI is the raising of TIF_NEED_RESCHED (and / or folding thereof into preempt_count); see scheduler_ipi() or sched_ttwu_pending() for instance. Said flag / preempt_count is evaluated some time later before returning to whatever context was interrupted, and this gates a call to preempt_schedule_irq() (arm64_preempt_schedule_irq() in arm64). Per the above, SGI's do not need a different handler than PPI's, so make them use the same (handle_percpu_devid_irq).

Dan reported that smatch reports wrong size check and after analysis it is confirmed that we are comparing wrong value: pointer size instead of array size. However the check itself is problematic as in UAPI header there are two fields: struct snd_soc_tplg_enum_control { (...) char texts[SND_SOC_TPLG_NUM_TEXTS][SNDRV_CTL_ELEM_ID_NAME_MAXLEN]; __le32 values[SND_SOC_TPLG_NUM_TEXTS * SNDRV_CTL_ELEM_ID_NAME_MAXLEN / 4]; the texts field is for names and the values one for values assigned to those named fields, after analysis it becomes clear that there is quite a lot overhead values than we may possibly name. So instead of changing check to ARRAY_SIZE(ec->values), as it was first suggested, use hardcoded value of SND_SOC_TPLG_NUM_TEXTS.

2020-12-11thermal/core: Emit a warning if the thermal zone is updated without opsDaniel Lezcano
The actual code is silently ignoring a thermal zone update when a driver is requesting it without a get_temp ops set. That looks not correct, as the caller should not have called this function if the thermal zone is unable to read the temperature. That makes the code less robust as the check won't detect the driver is inconsistently using the thermal API and that does not help to improve the framework as these circumvolutions hide the problem at the source. In order to detect the situation when it happens, let's add a warning when the update is requested without the get_temp() ops set. Any warning emitted will have to be fixed at the source of the problem: the caller must not call thermal_zone_device_update if there is not get_temp callback set.

2020-12-11thermal: devfreq_cooling: add new registration functions with Energy ModelLukasz Luba
The Energy Model (EM) framework supports devices such as Devfreq. Create new registration function which automatically register EM for the thermal devfreq_cooling devices. This patch prepares the code for coming changes which are going to replace old power model with the new EM.

2020-12-11thermal: devfreq_cooling: use a copy of device statusLukasz Luba
Devfreq cooling needs to now the correct status of the device in order to operate. Devfreq framework can change the device status in the background. To mitigate issues make a copy of the status structure and use it for internal calculations. In addition this patch adds normalization function, which also makes sure that whatever data comes from the device, the load will be in range from 1 to 1024.

2020-12-11ALSA: usb-audio: Fix control 'access overflow' errors from chmapTakashi Iwai
The current channel-map control implementation in USB-audio driver may lead to an error message like "control 3:0:0:Playback Channel Map:0: access overflow" when CONFIG_SND_CTL_VALIDATION is set. It's because the chmap get callback clears the whole array no matter which count is set, and rather the false-positive detection. This patch fixes the problem by clearing only the needed array range at usb_chmap_ctl_get().

The debug prints from patch_hdmi.c are not aligned with HDA common code in hda_codec.c nor with other HDA codec drivers. To align with rest of the codebase, use hexadecimal formatting whenever printing value of a HDA NID. Also refer to NIDs with capital letters in traces as is done other modules. This presentation is also aligned with the formatting used in HDA codec procfs entry.

2020-12-11nl80211: add common API to configure SAR power limitationsCarl Huang
NL80211_CMD_SET_SAR_SPECS is added to configure SAR from user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR power specification when used with NL80211_CMD_SET_SAR_SPECS. Wireless driver needs to register SAR type, supported frequency ranges to wiphy, so user space can query it. The index in frequency range is used to specify which sub band the power limitation applies to. The SAR type is for compatibility, so later other SAR mechanism can be implemented without breaking the user space SAR applications. Normal process is user space queries the SAR capability, and gets the index of supported frequency ranges and associates the power limitation with this index and sends to kernel. Here is an example of message send to kernel: 8c 00 00 00 08 00 01 00 00 00 00 00 38 00 2b 81 08 00 01 00 00 00 00 00 2c 00 02 80 14 00 00 80 08 00 02 00 00 00 00 00 08 00 01 00 38 00 00 00 14 00 01 80 08 00 02 00 01 00 00 00 08 00 01 00 48 00 00 00 NL80211_CMD_SET_SAR_SPECS: 0x8c NL80211_ATTR_WIPHY: 0x01(phy idx is 0) NL80211_ATTR_SAR_SPEC: 0x812b (NLA_NESTED) NL80211_SAR_ATTR_TYPE: 0x00 (NL80211_SAR_TYPE_POWER) NL80211_SAR_ATTR_SPECS: 0x8002 (NLA_NESTED) freq range 0 power: 0x38 in 0.25dbm unit (14dbm) freq range 1 power: 0x48 in 0.25dbm unit (18dbm) Signed-off-by: Carl Huang <cjhuang@codeaurora.org> Reviewed-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Abhishek Kumar <kuabhs@chromium.org> Link: https://lore.kernel.org/r/20201203103728.3034-2-cjhuang@codeaurora.org [minor edits, NLA parse cleanups] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

The ssid info of ieee80211_bss_conf is filled in ieee80211_start_ap() for AP mode. For STATION mode, it is empty, save the info from struct ieee80211_mgd_assoc_data, the struct ieee80211_mgd_assoc_data will be freed after assoc, so the ssid info of ieee80211_mgd_assoc_data can not access after assoc, save ssid info to ieee80211_bss_conf, then ssid info can be still access after assoc.
