Some of the newly added code in the etm4x driver is inside of an #ifdef, and some other code is outside of it, leading to a harmless warning when CONFIG_CPU_PM is disabled: drivers/hwtracing/coresight/coresight-etm4x.c:68:13: error: 'etm4_os_lock' defined but not used [-Werror=unused-function] static void etm4_os_lock(struct etmv4_drvdata *drvdata) ^~~~~~~~~~~~ To avoid the warning and simplify the the #ifdef checks, use IS_ENABLED() instead, so the compiler can drop the unused functions without complaining.

The driver was issuing synchronous uninterruptible control requests without using a timeout.

2020-01-13USB: serial: option: Add support for Quectel RM500QKristian Evensen
RM500Q is a 5G module from Quectel, supporting both standalone and non-standalone modes. Unlike other recent Quectel modems, it is possible to identify the diagnostic interface (bInterfaceProtocol is unique). Thus, there is no need to check for the number of endpoints or reserve interfaces. The interface number is still dynamic though, so matching on interface number is not possible and two entries have to be added to the table.

2020-01-13iio: buffer: align the size of scan bytes to size of the largest elementLars Möllendorf
Previous versions of `iio_compute_scan_bytes` only aligned each element to its own length (i.e. its own natural alignment). Because multiple consecutive sets of scan elements are buffered this does not work in case the computed scan bytes do not align with the natural alignment of the first scan element in the set. This commit fixes this by aligning the scan bytes to the natural alignment of the largest scan element in the set. Fixes: 959d2952d124 ("staging:iio: make iio_sw_buffer_preenable much more general.")

IIO triggered buffer depends on IIO buffer which is missing from Kconfig file. This should go unnoticed most of the time because there's a chance something else has already enabled buffers. In some rare cases though one might experience kbuild warnings about unmet direct dependencies and build failures due to missing symbols. Fix this by selecting IIO_BUFFER explicitly.

2020-01-13iio: imu: st_lsm6dsx: Fix selection of ST_LSM6DS3_IDStephan Gerhold
At the moment, attempting to probe a device with ST_LSM6DS3_ID (e.g. using the st,lsm6ds3 compatible) fails with: st_lsm6dsx_i2c 1-006b: unsupported whoami [69] ... even though 0x69 is the whoami listed for ST_LSM6DS3_ID. This happens because st_lsm6dsx_check_whoami() also attempts to match unspecified (zero-initialized) entries in the "id" array. ST_LSM6DS3_ID = 0 will therefore match any entry in st_lsm6dsx_sensor_settings (here: the first), because none of them actually have all 12 entries listed in the "id" array. Avoid this by additionally checking if "name" is set, which is only set for valid entries in the "id" array. Note: Although the problem was introduced earlier it did not surface until commit 52f4b1f19679 ("iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1") because ST_LSM6DS3_ID was the first entry in st_lsm6dsx_sensor_settings.

2020-01-13iio: adc: ad7124: Fix DT channel configurationAlexandru Tachici
This patch fixes device tree channel configuration. ad7124 driver reads channels configuration from the device tree. It expects to find channel specifications as child nodes. Before this patch ad7124 driver assumed that the child nodes are parsed by for_each_available_child_of_node in the order 0,1,2,3... This is wrong and the real order of the children can be seen by running: dtc -I fs /sys/firmware/devicetree/base on the machine. For example, running this on an rpi 3B+ yields the real children order: 4,2,0,7,5,3,1,6 Before this patch the driver assigned the channel configuration like this: - 0 <- 4 - 1 <- 2 - 2 <- 0 ........ For example, the symptoms can be observed by connecting the 4th channel to a 1V tension and then reading the in_voltage0-voltage19_raw sysfs (multiplied of course by the scale) one would see that channel 0 measures 1V and channel 4 measures only noise. Now the driver uses the reg property of each child in order to correctly identify to which channel the parsed configuration belongs to.

2020-01-13platform/x86: GPD pocket fan: Use default values when wrong modparams are givenHans de Goede
Use our default values when wrong module-parameters are given, instead of refusing to load. Refusing to load leaves the fan at the BIOS default setting, which is "Off". The CPU's thermal throttling should protect the system from damage, but not-loading is really not the best fallback in this case.

This commit fixes the potential deadlock caused by the console Rx and Tx processing at the same time. Rx and Tx both take the console and tmfifo spinlock but in different order which causes potential deadlock. The fix is to use different tmfifo spinlock for Rx and Tx since they protect different resources and it's safe to split the lock.
