2023-06-15drm/msm/dsi: update hdisplay calculation for dsi_timing_setupJessica Zhang
Currently, hdisplay is being divided by 3 for DSC. However, this calculation only works for cases where BPP = 8. Update hdisplay calculation to be bytes_per_line / 3, so that it accounts for cases where BPP != 8.

2023-06-15mfd: wm831x: Use maple tree register cacheMark Brown
regmap has introduced a maple tree based register cache which makes use of this more advanced data structure which has been added to the kernel recently. Maple trees are much flatter than rbtrees, meaning that they do not grow to such depths when the register map is sparse which makes access a bit more efficient. The maple tree cache type is still a bit of a work in progress but should be effective for some devices already. The wm831x devices have a pretty sparse register map and being always on devices never do cache syncs so don't hit the major current disadvantage so they should be good candiates for using the maple tree cache. Update to do so, there should be little if any visible difference at runtime.

2023-06-15mfd: intel-m10-bmc: Manage access to MAX 10 fw handshake registersIlpo Järvinen
On some MAX 10 cards, the BMC firmware is not available to service handshake registers during secure update erase and write phases at normal speeds. This problem affects at least hwmon driver. When the MAX 10 hwmon driver tries to read the sensor values during a secure update, the reads are slowed down (e.g., reading all D5005 sensors takes ~24s which is magnitudes worse than the normal <0.02s). Manage access to the handshake registers using a rw semaphore and a FW state variable to prevent accesses during those secure update phases and return -EBUSY instead. If handshake_sys_reg_nranges == 0, don't update bwcfw_state as it is not used. This avoids the locking cost.

2023-06-15net: tls: make the offload check helper take skb not socketJakub Kicinski
All callers of tls_is_sk_tx_device_offloaded() currently do an equivalent of: if (skb->sk && tls_is_skb_tx_device_offloaded(skb->sk)) Have the helper accept skb and do the skb->sk check locally. Two drivers have local static inlines with similar wrappers already. While at it change the ifdef condition to TLS_DEVICE. Only TLS_DEVICE selects SOCK_VALIDATE_XMIT, so the two are equivalent. This makes removing the duplicated IS_ENABLED() check in funeth more obviously correct.

2023-06-15Coresight: Add coresight dummy driverHao Zhang
Some Coresight devices that kernel don't have permission to access or configure. For these devices, a dummy driver is needed to register them as Coresight devices. The module may also be used to define components that may not have any programming interfaces, so that paths can be created in the driver. It provides Coresight API for operations on dummy devices, such as enabling and disabling them. It also provides the Coresight dummy sink/source paths for debugging.

2023-06-15s390/ism: Fix trying to free already-freed IRQ by repeated ism_dev_exit()Julian Ruess
This patch prevents the system from crashing when unloading the ISM module. How to reproduce: Attach an ISM device and execute 'rmmod ism'. Error-Log: - Trying to free already-free IRQ 0 - WARNING: CPU: 1 PID: 966 at kernel/irq/manage.c:1890 free_irq+0x140/0x540 After calling ism_dev_exit() for each ISM device in the exit routine, pci_unregister_driver() will execute ism_remove() for each ISM device. Because ism_remove() also calls ism_dev_exit(), free_irq(pci_irq_vector(pdev, 0), ism) is called twice for each ISM device. This results in a crash with the error 'Trying to free already-free IRQ'. In the exit routine, it is enough to call pci_unregister_driver() because it ensures that ism_dev_exit() is called once per ISM device.

2023-06-15wifi: mt7601u: replace strlcpy() with strscpy()Azeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since DEV_ASSIGN is only used by TRACE macros and the return values are ignored.

2023-06-15net: macb: Add support for partial store and forwardMaulik Jodhani
When the receive partial store and forward mode is activated, the receiver will only begin to forward the packet to the external AHB or AXI slave when enough packet data is stored in the packet buffer. The amount of packet data required to activate the forwarding process is programmable via watermark registers which are located at the same address as the partial store and forward enable bits. Adding support to read this rx-watermark value from device-tree, to program the watermark registers and enable partial store and forwarding.

2023-06-14net: dsa: felix: fix taprio guard band overflow at 10Mbps with jumbo framesVladimir Oltean
The DEV_MAC_MAXLEN_CFG register contains a 16-bit value - up to 65535. Plus 2 * VLAN_HLEN (4), that is up to 65543. The picos_per_byte variable is the largest when "speed" is lowest - SPEED_10 = 10. In that case it is (1000000L * 8) / 10 = 800000. Their product - 52434400000 - exceeds 32 bits, which is a problem, because apparently, a multiplication between two 32-bit factors is evaluated as 32-bit before being assigned to a 64-bit variable. In fact it's a problem for any MTU value larger than 5368. Cast one of the factors of the multiplication to u64 to force the multiplication to take place on 64 bits. Issue found by Coverity.

2023-06-14ice: Fix ice module unloadJakub Buchocki
Clearing the interrupt scheme before PFR reset, during the removal routine, could cause the hardware errors and possibly lead to system reboot, as the PF reset can cause the interrupt to be generated. Place the call for PFR reset inside ice_deinit_dev(), wait until reset and all pending transactions are done, then call ice_clear_interrupt_scheme(). This introduces a PFR reset to multiple error paths. Additionally, remove the call for the reset from ice_load() - it will be a part of ice_unload() now.
