[ Upstream commit 36a1da15 ] If CONFIG_OMAP4_DSS_HDMI_CEC is enabled in .config, deeper SoC idle states are blocked because the CEC clock gets always enabled on init. Let's fix the issue by moving the CEC clock handling to happen later in hdmi_cec_adap_enable() as suggested by Hans Verkuil <hverkuil@xs4all.nl>. This way the CEC clock gets only enabled when needed. This can be tested by doing cec-ctl --playback to enable the CEC, and doing cec-ctl --clear to disable it. Let's also fix the typo for "divider" in the comments while at it.

[ Upstream commit f0f2338a ] The CS4270 does not by default increment the register address on consecutive writes. During normal operation it doesn't matter as all register accesses are done individually. At resume time after suspend, however, the regcache code gathers the biggest possible block of registers to sync and sends them one on one go. To fix this, set the INCR bit in all cases.

[ Upstream commit 2b13bee3 ] After commit fbeec965b8d1c ("ASoC: samsung: odroid: Fix 32000 sample rate handling") the audio root clock frequency is configured improperly for 44100 sample rate. Due to clock rate rounding it's 20070401 Hz instead of 22579000 Hz. This results in a too low value of the PSR clock divider in the CPU DAI driver and too fast actual sample rate for fs=44100. E.g. 1 kHz tone has actual 1780 Hz frequency (1 kHz * 20070401/22579000 * 2). Fix this by increasing the correction passed to clk_set_rate() to take into account inaccuracy of the EPLL frequency properly.

[ Upstream commit 570f18b6 ] On HDaudio platforms, if playback is started when capture is working, there is no audible output. This can be root-caused to the use of the rx|tx_mask to store an HDaudio stream tag. If capture is stared before playback, rx_mask would be non-zero on HDaudio platform, then the channel number of playback, which is in the same codec dai with the capture, would be changed by soc_pcm_codec_params_fixup based on the tx_mask at first, then overwritten by this function based on rx_mask at last. According to the author of tx|rx_mask, tx_mask is for playback and rx_mask is for capture. And stream direction is checked at all other references of tx|rx_mask in ASoC, so here should be an error. This patch checks stream direction for tx|rx_mask for fixup function. This issue would affect not only HDaudio+ASoC, but also I2S codecs if the channel number based on rx_mask is not equal to the one for tx_mask. It could be rarely reproduecd because most drivers in kernel set the same channel number to tx|rx_mask or rx_mask is zero. Tested on all platforms using stream_tag & HDaudio and intel I2S platforms.

[ Upstream commit 2e95f984 ] When using the S/PDIF DAI, there is no requirement to call snd_soc_dai_set_fmt() as there is no DAI format definition that defines S/PDIF. In any case, S/PDIF does not have separate clocks, this is embedded into the data stream. Consequently, when attempting to use TDA998x in S/PDIF mode, the attempt to configure TDA998x via the hw_params callback fails as the hdmi_codec_daifmt is left initialised to zero. Since the S/PDIF DAI will only be used by S/PDIF, prepare the hdmi_codec_daifmt structure for this format. Signed-off-by:

[ Upstream commit 82ad7591 ] This patch fixes a bug that prevents freeing the reset gpio on unloading the module. aic3x_i2c_probe is called when loading the module and it calls list_add with a probably uninitialized list entry aic3x->list (next = prev = NULL)). So even if list_del is called it does nothing and in the end the gpio_reset is not freed. Then a repeated module probing fails silently because gpio_request fails. When moving INIT_LIST_HEAD to aic3x_i2c_probe we also have to move list_del to aic3x_i2c_remove because aic3x_remove may be called multiple times without aic3x_i2c_remove being called which leads to a NULL pointer dereference.

commit b90cd6f2 upstream. When the lldd is processing the complete sas task in interrupt and set the task stat as SAS_TASK_STATE_DONE, the smp timeout timer is able to be triggered at the same time. And smp_task_timedout() will complete the task wheter the SAS_TASK_STATE_DONE is set or not. Then the sas task may freed before lldd end the interrupt process. Thus a use-after-free will happen. Fix this by calling the complete() only when SAS_TASK_STATE_DONE is not set. And remove the check of the return value of the del_timer(). Once the LLDD sets DONE, it must call task->done(), which will call smp_task_done()->complete() and the task will be completed and freed correctly. Reported-by:

commit 61da76be upstream. The following commits: commit f6dd927f ("[media] media: ov7670: calculate framerate properly for ov7675") commit 04ee6d92 ("[media] media: ov7670: add possibility to bypass pll for ov7675") introduced the ability to bypass PLL multiplier and use input clock (xvclk) as pixel clock output frequency for ov7675 sensor. PLL is bypassed using register DBLV[7:6], according to ov7670 and ov7675 sensor manuals. Macros used to set DBLV register seem wrong in the driver, as their values do not match what reported in the datasheet. Fix by changing DBLV_* macros to use bits [7:6] and set bits [3:0] to default 0x0a reserved value (according to datasheets). While at there, remove a write to DBLV register in "ov7675_set_framerate()" that over-writes the previous one to the same register that takes "info->pll_bypass" flag into account instead of setting PLL multiplier to 4x unconditionally. And, while at there, since "info->pll_bypass" is only used in set/get_framerate() functions used by ov7675 only, it is not necessary to check for the device id at probe time to make sure that when using ov7670 "info->pll_bypass" is set to false.

commit ec393710 upstream. kernel_randomize_memory() uses __PHYSICAL_MASK_SHIFT to calculate the maximum amount of system RAM supported. The size of the direct mapping section is obtained from the smaller one of the below two values: (actual system RAM size + padding size) vs (max system RAM size supported) This calculation is wrong since commit b83ce5ee ("x86/mm/64: Make __PHYSICAL_MASK_SHIFT always 52"). In it, __PHYSICAL_MASK_SHIFT was changed to be 52, regardless of whether the kernel is using 4-level or 5-level page tables. Thus, it will always use 4 PB as the maximum amount of system RAM, even in 4-level paging mode where it should actually be 64 TB. Thus, the size of the direct mapping section will always be the sum of the actual system RAM size plus the padding size. Even when the amount of system RAM is 64 TB, the following layout will still be used. Obviously KALSR will be weakened significantly. |____|_______actual RAM_______|_padding_|______the rest_______| 0 64TB ~120TB Instead, it should be like this: |____|_______actual RAM_______|_________the rest______________| 0 64TB ~120TB The size of padding region is controlled by CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING, which is 10 TB by default. The above issue only exists when CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING is set to a non-zero value, which is the case when CONFIG_MEMORY_HOTPLUG is enabled. Otherwise, using __PHYSICAL_MASK_SHIFT doesn't affect KASLR. Fix it by replacing __PHYSICAL_MASK_SHIFT with MAX_PHYSMEM_BITS.

commit 78ad2341 upstream. Restore SW_CRYPTO_CONTROL operation on AP_VLAN interfaces for unicast keys, the original override was intended to be done for group keys as those are treated specially by mac80211 and would always have been rejected. Now the situation is that AP_VLAN support must be enabled by the driver if it can support it (meaning it can support software crypto GTK TX). Thus, also simplify the code - if we get here with AP_VLAN and non- pairwise key, software crypto must be used (driver doesn't know about the interface) and can be used (driver must've advertised AP_VLAN if it also uses SW_CRYPTO_CONTROL).

commit bf2a7ca3 upstream. SNVS IRQ is requested before necessary driver data initialized, if there is a pending IRQ during driver probe phase, kernel NULL pointer panic will occur in IRQ handler. To avoid such scenario, just initialize necessary driver data before enabling IRQ. This patch is inspired by NXP's internal kernel tree. Fixes: d3dc6e23 ("input: keyboard: imx: add snvs power key driver") Signed-off-by:
