ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE

2022-02-16T11:52:54+00:00

commit dc0075ba7f387fe4c48a8c674b11ab6f374a6acc upstream.

Commit 4a9af6cac050 ("ACPI: EC: Rework flushing of EC work while
suspended to idle") made acpi_ec_dispatch_gpe() check
pm_wakeup_pending(), but that is before canceling the SCI wakeup,
so pm_wakeup_pending() is always true.  This causes the loop in
acpi_ec_dispatch_gpe() to always terminate after one iteration which
may not be correct.

Address this issue by canceling the SCI wakeup earlier, from
acpi_ec_dispatch_gpe() itself.

Fixes: 4a9af6cac050 ("ACPI: EC: Rework flushing of EC work while suspended to idle")

scsi: lpfc: Remove NVMe support if kernel has NVME_FC disabled

2022-02-16T11:52:53+00:00

commit c80b27cfd93ba9f5161383f798414609e84729f3 upstream.

The driver is initiating NVMe PRLIs to determine device NVMe support.  This
should not be occurring if CONFIG_NVME_FC support is disabled.

Correct this by changing the default value for FC4 support. Currently it
defaults to FCP and NVMe. With change, when NVME_FC support is not enabled
in the kernel, the default value is just FCP.

hwmon: (dell-smm) Speed up setting of fan speed

2022-02-16T11:52:53+00:00

commit c0d79987a0d82671bff374c07f2201f9bdf4aaa2 upstream.

When setting the fan speed, i8k_set_fan() calls i8k_get_fan_status(),
causing an unnecessary SMM call since from the two users of this
function, only i8k_ioctl_unlocked() needs to know the new fan status
while dell_smm_write() ignores the new fan status.
Since SMM calls can be very slow while also making error reporting
difficult for dell_smm_write(), remove the function call from
i8k_set_fan() and call it separately in i8k_ioctl_unlocked().

Tested on a Dell Inspiron 3505.

USB: serial: ch341: add support for GW Instek USB2.0-Serial devices

2022-02-16T11:52:53+00:00

commit fa77ce201f7f2d823b07753575122d1ae5597fbe upstream.

Programmable lab power supplies made by GW Instek, such as the
GPP-2323, have a USB port exposing a serial port to control the device.

Stringing the supplied Windows driver, references to the ch341 chip are
found. Binding the existing ch341 driver to the VID/PID of the GPP-2323
("GW Instek USB2.0-Serial" as per the USB product name) works out of the
box, communication and control is now possible.

This patch should work with any GPP series power supply due to
similarities in the product line.

usb: gadget: f_uac2: Define specific wTerminalType

2022-02-16T11:52:53+00:00

commit 5432184107cd0013761bdfa6cb6079527ef87b95 upstream.

Several users have reported that their Win10 does not enumerate UAC2
gadget with the existing wTerminalType set to
UAC_INPUT_TERMINAL_UNDEFINED/UAC_INPUT_TERMINAL_UNDEFINED, e.g.
https://github.com/raspberrypi/linux/issues/4587#issuecomment-926567213.
While the constant is officially defined by the USB terminal types
document, e.g. XMOS firmware for UAC2 (commonly used for Win10) defines
no undefined output terminal type in its usbaudio20.h header.

Therefore wTerminalType of EP-IN is set to
UAC_INPUT_TERMINAL_MICROPHONE and wTerminalType of EP-OUT to
UAC_OUTPUT_TERMINAL_SPEAKER for the UAC2 gadget.
