[PATCH net v3 2/3] net: wangxun: revert the adjustment of the IRQ vector sequence

by Jiawen Wu

Due to hardware limitations of NGBE, queue IRQs can only be requested on vector 0 to 7. When the number of queues is set to the maximum 8, the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by MISC interrupt, and althrough the vector 8 is used by queue interrupt, it is unable to receive packets. This will cause some packets to be dropped when RSS is enabled and they are assigned to queue 8. So revert the adjustment of the MISC IRQ location, to make it be the last one in IRQ vectors.

[PATCH v2] wifi: wilc1000: Handle wilc_sdio_cmd52() failure in wilc_sdio_read_init()

by Wentao Liang

The wilc_sdio_read_init() calls wilc_sdio_cmd52() but does not check the return value. This could lead to execution with potentially invalid data if wilc_sdio_cmd52() fails. A proper implementation can be found in wilc_sdio_read_reg(). Add error handling for wilc_sdio_cmd52(). If wilc_sdio_cmd52() fails, log an error message via dev_err().

[PATCH v2 0/4] HID: avoid setting up battery timer when not needed in hid-apple and magicmouse

by Aditya Garg

Both hid-apple and hid-magicmouse require set up a battery timer for certain devices in order to fetch battery status. However, the timer is being set unconditionally for all devices. This patch series introduces checks to ensure that the battery timer is only set up for devices that actually require it. v2: - Address the cases of out_err and err_stop_hw left in v1 - Create a function to check if the device is a USB Magic Mouse 2 or Magic Trackpad 2 to reduce code duplication. - Add 2 new patches that convert the battery timeout to use secs_to_jiffies() instead of msecs_to_jiffies(). Aditya Garg (4): HID: apple: avoid setting up battery timer for devices without battery HID: magicmouse: avoid setting up battery timer when not needed HID: apple: use secs_to_jiffies() for battery timeout HID: magicmouse: use secs_to_jiffies() for battery timeout drivers/hid/hid-apple.c | 21 +++++++----- drivers/hid/hid-magicmouse.c | 66 ++++++++++++++++++++++-------------- 2 files changed, 54 insertions(+), 33 deletions(-) Range-diff against v1: 1: 05b6ac964 !

Clarifies in the function documentation that instance_id refers to a logical ID 2. Adds conversion from logical to physical instance ID before performing reset using GET_INST(SDMA0, instance_id) macro 3. Improves error messaging to indicate when a logical instance reset fails 4. Adds better code organization with blank lines for readability The change ensures proper SDMA engine reset by using the correct physical instance ID while maintaining the logical ID interface for callers.
