2019-01-08ASoC: rt274: Variable "buf" in function rt274_jack_detect() could be ↵Yizhuo
uninitialized In function rt274_jack_detect(), local variable "buf" could be uninitialized if function regmap_read() returns -EINVAL. However, it will be used to calculate "hp" and "mic" and make their value unpredictable while those value are used in the caller. This is potentially unsafe.

2019-01-08ASoC: ADAU7002: Add optional delay before start of captureAgrawal, Akshu
On capture through some of dmic we observe a glitch at the start of record. This is because we start capturing even before dmic is ready to send out data.

2019-01-08dma-mapping: remove dma_zalloc_coherent()Luis Chamberlain
dma_zalloc_coherent() is no longer needed as it has no users because dma_alloc_coherent() already zeroes out memory for us. The Coccinelle grammar rule that used to check for dma_alloc_coherent() + memset() is modified so that it just tells the user that the memset is not needed anymore.

2019-01-08mtd: rawnand: qcom: fix memory corruption that causes panicChristian Lamparter
This patch fixes a memory corruption that occurred in the qcom-nandc driver since it was converted to nand_scan(). On boot, an affected device will panic from a NPE at a weird place: | Unable to handle kernel NULL pointer dereference at virtual address 0 | pgd = (ptrval) | [00000000] *pgd=00000000 | Internal error: Oops: 80000005 [#1] SMP ARM | CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.19.9 #0 | Hardware name: Generic DT based system | PC is at (null) | LR is at nand_block_isbad+0x90/0xa4 | pc : [<00000000>] lr : [<c0592240>] psr: 80000013 | sp : cf839d40 ip : 00000000 fp : cfae9e20 | r10: cf815810 r9 : 00000000 r8 : 00000000 | r7 : 00000000 r6 : 00000000 r5 : 00000001 r4 : cf815810 | r3 : 00000000 r2 : cfae9810 r1 : ffffffff r0 : cf815810 | Flags: Nzcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none | Control: 10c5387d Table: 8020406a DAC: 00000051 | Process swapper/0 (pid: 1, stack limit = 0x(ptrval)) | [<c0592240>] (nand_block_isbad) from [<c0580a94>] | [<c0580a94>] (allocate_partition) from [<c05811e4>] | [<c05811e4>] (add_mtd_partitions) from [<c0581164>] | [<c0581164>] (parse_mtd_partitions) from [<c057def4>] | [<c057def4>] (mtd_device_parse_register) from [<c059d274>] | [<c059d274>] (qcom_nandc_probe) from [<c0567f00>] The problem is that the nand_scan()'s qcom_nand_attach_chip callback is updating the nandc->max_cwperpage from 1 to 4. This causes the sg_init_table of clear_bam_transaction() in the driver's qcom_nandc_block_bad() to memset much more than what was initially allocated by alloc_bam_transaction(). This patch restores the old behavior by reallocating the shared bam transaction alloc_bam_transaction() after the chip was identified, but before mtd_device_parse_register() (which is an alias for mtd_device_register() - see panic) gets called. This fixes the corruption and the driver is working again.

2019-01-08cpufreq: check if policy is inactive early in __cpufreq_get()Sudeep Holla
cpuinfo_cur_freq gets current CPU frequency as detected by hardware while scaling_cur_freq last known CPU frequency. Some platforms may not allow checking the CPU frequency of an offline CPU or the associated resources may have been released via cpufreq_exit when the CPU gets offlined, in which case the policy would have been invalidated already. If we attempt to get current frequency from the hardware, it may result in hang or crash. For example on Juno, I see: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000188 [0000000000000188] pgd=0000000000000000 Internal error: Oops: 96000004 [#1] PREEMPT SMP Modules linked in: CPU: 5 PID: 4202 Comm: cat Not tainted 4.20.0-08251-ga0f2c0318a15-dirty #87 Hardware name: ARM LTD ARM Juno Development Platform/ARM Juno Development Platform pstate: 40000005 (nZcv daif -PAN -UAO) pc : scmi_cpufreq_get_rate+0x34/0xb0 lr : scmi_cpufreq_get_rate+0x34/0xb0 Call trace: scmi_cpufreq_get_rate+0x34/0xb0 __cpufreq_get+0x34/0xc0 show_cpuinfo_cur_freq+0x24/0x78 show+0x40/0x60 sysfs_kf_seq_show+0xc0/0x148 kernfs_seq_show+0x44/0x50 seq_read+0xd4/0x480 kernfs_fop_read+0x15c/0x208 __vfs_read+0x60/0x188 vfs_read+0x94/0x150 ksys_read+0x6c/0xd8 __arm64_sys_read+0x24/0x30 el0_svc_common+0x78/0x100 el0_svc_handler+0x38/0x78 el0_svc+0x8/0xc ---[ end trace 3d1024e58f77f6b2 ]--- So fix the issue by checking if the policy is invalid early in __cpufreq_get before attempting to get the current frequency.

2019-01-07MIPS: lantiq: Fix IPI interrupt handlingHauke Mehrtens
This makes SMP on the vrx200 work again, by removing all the MIPS CPU interrupt specific code and making it fully use the generic MIPS CPU interrupt controller. The mti,cpu-interrupt-controller from irq-mips-cpu.c now handles the CPU interrupts and also the IPI interrupts which are used to communication between the CPUs in a SMP system. The generic interrupt code was already used before but the interrupt vectors were overwritten again when we called set_vi_handler() in the lantiq interrupt driver and we also provided our own plat_irq_dispatch() function which overwrote the weak generic implementation. Now the code uses the generic handler for the MIPS CPU interrupts including the IPI interrupts and registers a handler for the CPU interrupts which are handled by the lantiq ICU with irq_set_chained_handler() which was already called before. Calling the set_c0_status() function is also not needed any more because the generic MIPS CPU interrupt already activates the needed bits.

Commit 37c7401e8c1f ("ASoC: Intel: bytcr_rt5651: Fix DMIC map headsetmic mapping"), changed the headsetmic mapping from IN3P to IN2P, this was based on the observation that all bytcr_rt5651 devices I have access to (7 devices) where all using IN3P for the headsetmic. This was an attempt to unifify / simplify the mapping, but it was wrong. None of those devices was actually using a digital internal mic. Now I've access to a Point of View TAB-P1006W-232 (v1.0) tabler, which does use a DMIC and it does have its headsetmic connected to IN2P, showing that the original mapping was correct, so this commit reverts the change changing the mapping back to IN2P.

Like the rt5645 and rt5670 drivers which also have the 10EC5640 ACPI HID in their acpi_device_id list for similar reasons, the rt5651 driver checks the codecs device-id register so that it will only bind if the codec actually is a rt5651 and it will ignore actual rt5640 codecs.

Commit 8097e53eaba2 ("ACPI/IORT: Use helper functions to access dev->iommu_fwspec") changed by mistake the iort_fwspec_iommu_ops() stub definition (compiled in when CONFIG_IOMMU_API=n), that caused the following compilation failure: drivers/acpi/arm64/iort.c:880:1: error: expected identifier or '(' before '{' token { return NULL; } ^ drivers/acpi/arm64/iort.c:879:39: warning: 'iort_fwspec_iommu_ops' used but never defined static inline const struct iommu_ops *iort_fwspec_iommu_ops(struct device *dev); ^~~~~~~~~~~~~~~~~~~~~ Fix it.

2019-01-07net: bridge: fix a bug on using a neighbour cache entry without checking its ↵JianJhen Chen
state When handling DNAT'ed packets on a bridge device, the neighbour cache entry from lookup was used without checking its state. It means that a cache entry in the NUD_STALE state will be used directly instead of entering the NUD_DELAY state to confirm the reachability of the neighbor. This problem becomes worse after commit 2724680bceee ("neigh: Keep neighbour cache entries if number of them is small enough."), since all neighbour cache entries in the NUD_STALE state will be kept in the neighbour table as long as the number of cache entries does not exceed the value specified in gc_thresh1. This commit validates the state of a neighbour cache entry before using the entry.

2019-01-07ASoC: tlv320aic32x4: Kernel OOPS while entering DAPM standby modeb-ak
During the bootup of the kernel, the DAPM bias level is in the OFF state. As soon as the DAPM framework kicks in it pushes the codec into STANDBY state. The probe function doesn't prepare the clock, and STANDBY state does a clk_disable_unprepare() without checking the previous state. This leads to an OOPS. Not transitioning from an OFF state to the STANDBY state fixes the problem. Signed-off-by: b-ak <anur.bhargav@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
