2023-01-19net: dsa: microchip: ksz9477: port map correction in ALU table entry registerRakesh Sankaranarayanan1-2/+2
ALU table entry 2 register in KSZ9477 have bit positions reserved for forwarding port map. This field is referred in ksz9477_fdb_del() for clearing forward port map and alu table. But current fdb_del refer ALU table entry 3 register for accessing forward port map. Update ksz9477_fdb_del() to get forward port map from correct alu table entry register. With this bug, issue can be observed while deleting static MAC entries. Delete any specific MAC entry using "bridge fdb del" command. This should clear all the specified MAC entries. But it is observed that entries with self static alone are retained. Tested on LAN9370 EVB since ksz9477_fdb_del() is used common across LAN937x and KSZ series.

2023-01-19comedi: adv_pci1760: Fix PWM instruction handlingIan Abbott1-1/+1
(Actually, this is fixing the "Read the Current Status" command sent to the device's outgoing mailbox, but it is only currently used for the PWM instructions.) The PCI-1760 is operated mostly by sending commands to a set of Outgoing Mailbox registers, waiting for the command to complete, and reading the result from the Incoming Mailbox registers. One of these commands is the "Read the Current Status" command. The number of this command is 0x07 (see the User's Manual for the PCI-1760 at <https://advdownload.advantech.com/productfile/Downloadfile2/1-11P6653/PCI-1760.pdf>. The `PCI1760_CMD_GET_STATUS` macro defined in the driver should expand to this command number 0x07, but unfortunately it currently expands to 0x03. (Command number 0x03 is not defined in the User's Manual.) Correct the definition of the `PCI1760_CMD_GET_STATUS` macro to fix it. This is used by all the PWM subdevice related instructions handled by `pci1760_pwm_insn_config()` which are probably all broken. The effect of sending the undefined command number 0x03 is not known.

2023-01-19serial: atmel: fix incorrect baudrate setupTobias Schramm1-7/+1
Commit ba47f97a18f2 ("serial: core: remove baud_rates when serial console setup") changed uart_set_options to select the correct baudrate configuration based on the absolute error between requested baudrate and available standard baudrate settings. Prior to that commit the baudrate was selected based on which predefined standard baudrate did not exceed the requested baudrate. This change of selection logic was never reflected in the atmel serial driver. Thus the comment left in the atmel serial driver is no longer accurate. Additionally the manual rounding up described in that comment and applied via (quot - 1) requests an incorrect baudrate. Since uart_set_options uses tty_termios_encode_baud_rate to determine the appropriate baudrate flags this can cause baudrate selection to fail entirely because tty_termios_encode_baud_rate will only select a baudrate if relative error between requested and selected baudrate does not exceed +/-2%. Fix that by requesting actual, exact baudrate used by the serial.

2023-01-19serial: stm32: Merge hard IRQ and threaded IRQ handling into single IRQ handlerMarek Vasut1-27/+4
Requesting an interrupt with IRQF_ONESHOT will run the primary handler in the hard-IRQ context even in the force-threaded mode. The force-threaded mode is used by PREEMPT_RT in order to avoid acquiring sleeping locks (spinlock_t) in hard-IRQ context. This combination makes it impossible and leads to "sleeping while atomic" warnings. Use one interrupt handler for both handlers (primary and secondary) and drop the IRQF_ONESHOT flag which is not needed.

2023-01-19tty: serial: qcom-geni-serial: fix slab-out-of-bounds on RX FIFO bufferKrzysztof Kozlowski1-2/+16
Driver's probe allocates memory for RX FIFO (port->rx_fifo) based on default RX FIFO depth, e.g. 16. Later during serial startup the qcom_geni_serial_port_setup() updates the RX FIFO depth (port->rx_fifo_depth) to match real device capabilities, e.g. to 32. The RX UART handle code will read "port->rx_fifo_depth" number of words into "port->rx_fifo" buffer, thus exceeding the bounds.

But there are only two ->aura_freeptr() callbacks, otx2_aura_freeptr() and cn10k_aura_freeptr(). There is no usage of perpcu variable in the otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it. We can move the get/put_cpu() into the corresponding callback which really has the percpu variable usage and avoid the sprinkling of get/put_cpu() in several places.

2023-01-19nvme-pci: fix timeout request state checkKeith Busch1-1/+1
Polling the completion can progress the request state to IDLE, either inline with the completion, or through softirq. Either way, the state may not be COMPLETED, so don't check for that. We only care if the state isn't IN_FLIGHT. This is fixing an issue where the driver aborts an IO that we just completed. Seeing the "aborting" message instead of "polled" is very misleading as to where the timeout problem resides.

This is a functional revert of c76b8308e4c9 ("nvme-apple: fix controller shutdown in apple_nvme_disable"). The commit broke suspend/resume since apple_nvme_reset_work() tries to disable the controller on resume. This does not work for the apple NVMe controller since register access only works while the co-processor firmware is running. Disabling the NVMe controller in the shutdown path is also required for shutting the co-processor down. The original code was appropriate for this hardware. Add a comment to prevent a similar breaking changes in the future.

2023-01-18Revert "net: team: use IFF_NO_ADDRCONF flag to prevent ipv6 addrconf"Xin Long1-2/+0
This reverts commit 0aa64df30b382fc71d4fb1827d528e0eb3eff854. Currently IFF_NO_ADDRCONF is used to prevent all ipv6 addrconf for the slave ports of team, bonding and failover devices and it means no ipv6 packets can be sent out through these slave ports. However, for team device, "nsna_ping" link_watch requires ipv6 addrconf. Otherwise, the link will be marked failure. This patch removes the IFF_NO_ADDRCONF flag set for team port, and we will fix the original issue in another patch, as Jakub suggested.

Currently, we run into a number of WARN()s when attempting to unload the amdgpu driver (e.g. using "modprobe -r amdgpu"). These all stem from calling drm_encoder_cleanup() too early. So, to fix this we can stop calling drm_encoder_cleanup() from amdgpu_dm_fini() and instead have it be called from amdgpu_dm_encoder_destroy(). Also, we don't need to free in amdgpu_dm_encoder_destroy() since mst_encoders[] isn't explicitly allocated by the slab allocator.

2023-01-18gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xRUMario Limonciello1-0/+13
commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable") changed the policy such that I2C touchpads may be able to wake up the system by default if the system is configured as such. However on Clevo NL5xRU there is a mistake in the ACPI tables that the TP_ATTN# signal connected to GPIO 9 is configured as ActiveLow and level triggered but connected to a pull up. As soon as the system suspends the touchpad loses power and then the system wakes up. To avoid this problem, introduce a quirk for this model that will prevent the wakeup capability for being set for GPIO 9.

2023-01-18gpiolib: acpi: Allow ignoring wake capability on pins that aren't in _AEIMario Limonciello1-2/+2
Using the `ignore_wake` quirk or module parameter doesn't work for any pin that has been specified in the _CRS instead of _AEI. Extend the `acpi_gpio_irq_is_wake` check to cover both places.
