The bug is here: return cluster; The list iterator value 'cluster' will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found. To fix the bug, return 'cluster' when found, otherwise return NULL.

2022-04-04mtd: rawnand: fix ecc parameters for mt7622Chuanhong Guo
According to the datasheet, mt7622 only has 5 ECC capabilities instead of 7, and the decoding error register is arranged as follows: +------+---------+---------+---------+---------+ | Bits | 19:15 | 14:10 | 9:5 | 4:0 | +------+---------+---------+---------+---------+ | Name | ERRNUM3 | ERRNUM2 | ERRNUM1 | ERRNUM0 | +------+---------+---------+---------+---------+ This means err_mask should be 0x1f instead of 0x3f and the number of bits shifted in mtk_ecc_get_stats should be 5 instead of 8. This commit introduces err_shift for the difference in this register and fix other existing parameters. Public MT7622 reference manual can be found on [0] and the info this commit is based on is from page 656 and page 660.

2022-04-04iio:proximity:sx9324: Fix hardware gain read/writeStephen Boyd
There are four possible gain values according to 'sx9324_gain_vals[]': 1, 2, 4, and 8 The values are off by one when writing and reading the register. The bits should be set according to this equation: ilog2(<gain>) + 1 so that a gain of 8 is 0x4 in the register field and a gain of 4 is 0x3 in the register field, etc. Note that a gain of 0 is reserved per the datasheet. The default gain (SX9324_REG_PROX_CTRL0_GAIN_1) is also wrong. It should be 0x1 << 3, i.e. 0x8, not 0x80 which is setting the reserved bit 7. Fix this all up to properly handle the hardware gain and return errors for invalid settings.

2022-04-04iio:proximity:sx_common: Fix device property parsing on DT systemsStephen Boyd
After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we started using the 'indio_dev->dev' to extract device properties for various register settings in sx9310_get_default_reg(). This broke DT based systems because dev_fwnode() used in the device_property*() APIs can't find an 'of_node'. That's because the 'indio_dev->dev.of_node' pointer isn't set until iio_device_register() is called. Set the pointer earlier, next to where the ACPI companion is set, so that the device property APIs work on DT systems.

2022-04-04iio: dac: dac5571: Fix chip id detection for OF devicesJose Cazarin
When matching an OF device, the match mechanism tries all components of the compatible property. This can result with a device matched with a compatible string that isn't the first in the compatible list. For instance, with a compatible property set to compatible = "ti,dac081c081", "ti,dac5571"; the driver will match the second compatible string, as the first one isn't listed in the of_device_id table. The device will however be named "dac081c081" by the I2C core. This causes an issue when identifying the chip. The probe function receives a i2c_device_id that comes from the module's I2C device ID table. There is no entry in that table for "dac081c081", which results in a NULL pointer passed to the probe function. To fix this, add chip_id information in the data field of the OF device ID table, and retrieve it with device_get_match_data() for OF devices.

As per Table 130 of the wm8994 datasheet at [1], there is an off-on delay for LDO1 and LDO2. In the wm8958 datasheet [2], I could not find any reference to it.

2022-04-04firmware: arm_scmi: Remove clear channel call on the TX channelCristian Marussi
On SCMI transports whose channels are based on a shared resource the TX channel area has to be acquired by the agent before placing the desired command into the channel and it will be then relinquished by the platform once the related reply has been made available into the channel. On an RX channel the logic is reversed with the platform acquiring the channel area and the agent reliquishing it once done by calling the scmi_clear_channel() helper. As a consequence, even in case of error, the agent must never try to clear a TX channel from its side: restrict the existing clear channel call on the the reply path only to delayed responses since they are indeed coming from the RX channel.

2022-04-04cpufreq: qcom-cpufreq-hw: Fix throttle frequency value on EPSS platformsVladimir Zapolskiy
On QCOM platforms with EPSS flavour of cpufreq IP a throttled frequency is obtained from another register REG_DOMAIN_STATE, thus the helper function qcom_lmh_get_throttle_freq() should be modified accordingly, as for now it returns gibberish since .reg_current_vote is unset for EPSS hardware. To exclude a hardcoded magic number 19200 it is replaced by "xo" clock rate in KHz.

Samsung' 840 EVO with the latest firmware (EXT0DB6Q) locks up with the a message: "READ LOG DMA EXT failed, trying PIO" during boot. Initially this was discovered because it caused a crash with the sata_dwc_460ex controller on a WD MyBook Live DUO. The reporter "Tice Rex" which has the unique opportunity that he has two Samsung 840 EVO SSD! One with the older firmware "EXT0BB0Q" which booted fine and didn't expose "READ LOG DMA EXT". But the newer/latest firmware "EXT0DB6Q" caused the headaches.

the driver uses libata's "tag" values from in various arrays. Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32, the value of the SATA_DWC_QCMD_MAX needs to account for that. Otherwise ATA_TAG_INTERNAL usage cause similar crashes like this as reported by Tice Rex on the OpenWrt Forum and reproduced (with symbols) here: | BUG: Kernel NULL pointer dereference at 0x00000000 | Faulting instruction address: 0xc03ed4b8 | Oops: Kernel access of bad area, sig: 11 [#1] | BE PAGE_SIZE=4K PowerPC 44x Platform | CPU: 0 PID: 362 Comm: scsi_eh_1 Not tainted 5.4.163 #0 | NIP: c03ed4b8 LR: c03d27e8 CTR: c03ed36c | REGS: cfa59950 TRAP: 0300 Not tainted (5.4.163) | MSR: 00021000 <CE,ME> CR: 42000222 XER: 00000000 | DEAR: 00000000 ESR: 00000000 | GPR00: c03d27e8 cfa59a08 cfa55fe0 00000000 0fa46bc0 [...] | [..] | NIP [c03ed4b8] sata_dwc_qc_issue+0x14c/0x254 | LR [c03d27e8] ata_qc_issue+0x1c8/0x2dc | Call Trace: | [cfa59a08] [c003f4e0] __cancel_work_timer+0x124/0x194 (unreliable) | [cfa59a78] [c03d27e8] ata_qc_issue+0x1c8/0x2dc | [cfa59a98] [c03d2b3c] ata_exec_internal_sg+0x240/0x524 | [cfa59b08] [c03d2e98] ata_exec_internal+0x78/0xe0 | [cfa59b58] [c03d30fc] ata_read_log_page.part.38+0x1dc/0x204 | [cfa59bc8] [c03d324c] ata_identify_page_supported+0x68/0x130 | [...] This is because sata_dwc_dma_xfer_complete() NULLs the dma_pending's next neighbour "chan" (a *dma_chan struct) in this '32' case right here (line ~735): > hsdevp->dma_pending[tag] = SATA_DWC_DMA_PENDING_NONE; Then the next time, a dma gets issued; dma_dwc_xfer_setup() passes the NULL'd hsdevp->chan to the dmaengine_slave_config() which then causes the crash. With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1. This avoids the OOB. But please note, there was a worthwhile discussion on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not be a "fake" 33 command-long queue size. Ideally, the dw driver should account for the ATA_TAG_INTERNAL. In Damien Le Moal's words: "... having looked at the driver, it is a bigger change than just faking a 33rd "tag" that is in fact not a command tag at all."

2022-04-01net: stmmac: Fix unset max_speed difference between DT and non-DT platformsChen-Yu Tsai
In commit 9cbadf094d9d ("net: stmmac: support max-speed device tree property"), when DT platforms don't set "max-speed", max_speed is set to -1; for non-DT platforms, it stays the default 0. Prior to commit eeef2f6b9f6e ("net: stmmac: Start adding phylink support"), the check for a valid max_speed setting was to check if it was greater than zero. This commit got it right, but subsequent patches just checked for non-zero, which is incorrect for DT platforms. In commit 92c3807b9ac3 ("net: stmmac: convert to phylink_get_linkmodes()") the conversion switched completely to checking for non-zero value as a valid value, which caused 1000base-T to stop getting advertised by default. Instead of trying to fix all the checks, simply leave max_speed alone if DT property parsing fails.

2022-04-01net/fungible: Fix reference to __udivdi3 on 32b buildsDimitris Michailidis
32b builds with CONFIG_PHYS_ADDR_T_64BIT=y, such as i386 PAE, raise a linker error due to a 64b division: ld: drivers/net/ethernet/fungible/funcore/fun_dev.o: in function `fun_dev_enable': (.text+0xe1a): undefined reference to `__udivdi3' The divisor in the offendinng expression is a power of 2.
