commit 1e9b71d5 upstream. Recently, an unfinished patch was merged that added a third entry to the beginning of the array of firmware locations without changing the code to also look at the third element, thus pushing an old firmware location off the list.

commit dd14a3e9 upstream. The timeout for BULK packets was 300ms which is a long time if other endpoints or devices are waiting for their turn. Changing it to 50ms greatly increased the overall performance for multi-endpoint devices. Fixes: 5d304358 ("usb: r8a66597-hcd: host controller driver for R8A6659") Signed-off-by:

commit 1f873d85 upstream. If multiple endpoints on a single device have pending IN URBs and one endpoint times out due to NAKs (perfectly legal), select a different endpoint URB to try. The existing code only checked to see another device address has pending URBs and ignores other IN endpoints on the current device address. This leads to endpoints never getting serviced if one endpoint is using NAK as a flow control method. Fixes: 5d304358 ("usb: r8a66597-hcd: host controller driver for R8A6659") Signed-off-by:

commit 6830733d upstream. The driver uses a relatively large data structure on the stack, which showed up on my radar as we get a warning with the "latent entropy" GCC plugin: drivers/media/usb/pvrusb2/pvrusb2-eeprom.c:153:1: error: the frame size of 1376 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] The warning is usually hidden as we raise the warning limit to 2048 when the plugin is enabled, but I'd like to lower that again in the future, and making this function smaller helps to do that without build regressions. Further analysis shows that putting an 'i2c_client' structure on the stack is not really supported, as the embedded 'struct device' is not initialized here, and we are only saved by the fact that the function that is called here does not use the pointer at all.

commit f1d6826c upstream. Commit 08a36b54 ("usb: dwc3: gadget: simplify __dwc3_gadget_ep_queue()") caused a small change in the way ISO transfer is handled in the case when XferInProgress event happens on Isoc EP with an active transfer. This caused a performance degradation of 50%. e.g. using g_webcam on DUT and luvcview on host the video frame rate dropped from 16fps to 8fps @high-speed. Make the ISO transfer handling equivalent to that prior to that commit to get back the original ISO performance numbers.

commit ec963b41 upstream. Fix up the root-hub descriptor to accommodate the variable-length DeviceRemovable and PortPwrCtrlMask fields, while marking all ports as removable (and leaving the reserved bit zero unset). Also add a build-time constraint on VHCI_HC_PORTS which must never be greater than USB_MAXCHILDREN (but this was only enforced through a KConfig constant). This specifically fixes the descriptor layout whenever VHCI_HC_PORTS is greater than seven (default is 8).

commit 2ccc1503 upstream. This patch allows to avoid a transitory that occurs when a given sensor has been already enabled (e.g. gyroscope) and the user is configuring the sample frequency of the other one (e.g. accelerometer). The transitory lasts until the accelerometer is enabled. During that time slice the gyroscope ODR is incorrectly modified as well. At the end of the transitory both sensors work at the right frequency. Fix it introducing st_lsm6dsx_check_odr() routine to check ODR consistency in write_raw handler in order to apply frequency configuration just in st_lsm6dsx_set_odr() Fixes: 290a6ce1 (iio: imu: add support to lsm6dsx driver) Signed-off-by:

commit aaa22952 upstream. The current page table dumper scans the Linux page tables and coalesces mappings with adjacent virtual addresses and similar PTE flags. This behaviour is somewhat broken when you consider the IOREMAP space where entirely unrelated mappings will appear to be virtually contiguous. This patch modifies the range coalescing so that only ranges that are both physically and virtually contiguous are combined.

commit ac894732 upstream. I made a mistake assuming the device tree configuration for interrupt triggering was somehow passed to the SPI device but it's not. In the Motorola Linux kernel tree CPCAP PMIC is configured as a rising edge triggered interrupt, but then then it's interrupt handler keeps looping until the GPIO line goes down. So the CPCAP interrupt is clearly a level interrupt and not an edge interrupt. Earlier when I tried to configure it as level interrupt using the device tree, I did not account that the triggering only gets passed to the SPI core and it also needs to be specified in the CPCAP driver when we do devm_regmap_add_irq_chip().

commit 5f76895e upstream. When changing hardware control flow for a UART with dedicated RTS/CTS pins, the new AUTORTS state is not immediately reflected in the hardware, but only when RTS is raised. However, the serial core does not call .set_mctrl() after .set_termios(), hence AUTORTS may only become effective when the port is closed, and reopened later. Note that this problem does not happen when manually using stty to change CRTSCTS, as AUTORTS will work fine on next open. To fix this, call .set_mctrl() from .set_termios() when dedicated RTS/CTS pins are present, to refresh the AUTORTS or RTS state. This is similar to what other drivers supporting AUTORTS do (e.g. omap-serial). Reported-by:

commit cfa6eb23 upstream. If a UART has dedicated RTS/CTS pins, and hardware control flow is disabled (or AUTORTS is not yet effective), changing any serial port configuration deasserts RTS, as .set_termios() calls sci_init_pins(). To fix this, consider the current (AUTO)RTS state when (re)initializing the pins. Note that for SCIFA/SCIFB, AUTORTS needs explicit configuration of the RTS# pin function, while (H)SCIF handles this automatically.

commit b3dd8279 upstream. mac80211 allows to modify the SMPS state of an AP both, when it is started, and after it has been started. Such a change will trigger an action frame to all the peers that are currently connected, and will be remembered so that new peers will get notified as soon as they connect (since the SMPS setting in the beacon may not be the right one). This means that we need to remember the SMPS state currently requested as well as the SMPS state that was configured initially (and advertised in the beacon). The former is bss->req_smps and the latter is sdata->smps_mode. Initially, the AP interface could only be started with SMPS_OFF, which means that sdata->smps_mode was SMPS_OFF always. Later, a nl80211 API was added to be able to start an AP with a different AP mode. That code forgot to update bss->req_smps and because of that, if the AP interface was started with SMPS_DYNAMIC, we had: sdata->smps_mode = SMPS_DYNAMIC bss->req_smps = SMPS_OFF That configuration made mac80211 think it needs to fire off an action frame to any new station connecting to the AP in order to let it know that the actual SMPS configuration is SMPS_OFF. Fix that by properly setting bss->req_smps in ieee80211_start_ap. Fixes: f6993174 ("mac80211: set smps_mode according to ap params") Signed-off-by:
