iio: tsl2583: Fix division by a zero lux_val

2021-05-22T08:59:46+00:00

commit af0e1871d79cfbb91f732d2c6fa7558e45c31038 upstream.

The lux_val returned from tsl2583_get_lux can potentially be zero,
so check for this to avoid a division by zero and an overflowed
gain_trim_val.

Fixes clang scan-build warning:

drivers/iio/light/tsl2583.c:345:40: warning: Either the
condition 'lux_val<0' is redundant or there is division
by zero at line 345. [zerodivcond]

iio: gyro: mpu3050: Fix reported temperature value

2021-05-22T08:59:46+00:00

commit f73c730774d88a14d7b60feee6d0e13570f99499 upstream.

The raw temperature value is a 16-bit signed integer. The sign casting
is missing in the code, which results in a wrong temperature reported
by userspace tools, fix it.

iio: proximity: pulsedlight: Fix rumtime PM imbalance on error

2021-05-22T08:59:45+00:00

[ Upstream commit a2fa9242e89f27696515699fe0f0296bf1ac1815 ]

When lidar_write_control() fails, a pairing PM usage counter
decrement is needed to keep the counter balanced.

iio:accel:adis16201: Fix wrong axis assignment that prevents loading

2021-05-22T08:59:24+00:00

commit 4e102429f3dc62dce546f6107e34a4284634196d upstream.

Whilst running some basic tests as part of writing up the dt-bindings for
this driver (to follow), it became clear it doesn't actually load
currently.

iio iio:device1: tried to double register : in_incli_x_index
adis16201 spi0.0: Failed to create buffer sysfs interfaces
adis16201: probe of spi0.0 failed with error -16

Looks like a cut and paste / update bug.  Fixes tag obviously not accurate
but we don't want to bother carry thing back to before the driver moved
out of staging.

commit 141e7633aa4d2838d1f6ad5c74cccc53547c16ac upstream.

This patch fixes 2 issues of timestamp channel:
1. This patch ensures that there is sufficient space and correct
alignment for the timestamp.
2. Correct the timestamp channel scan index.

iio: hid-sensor-prox: Fix scale not correct issue

2021-03-24T10:07:36+00:00

commit d68c592e02f6f49a88e705f13dfc1883432cf300 upstream.

Currently, the proxy sensor scale is zero because it just return the
exponent directly. To fix this issue, this patch use
hid_sensor_format_scale to process the scale first then return the
output.

iio: adis16400: Fix an error code in adis16400_initial_setup()

commit a71266e454b5df10d019b06f5ebacd579f76be28 upstream.

This is to silence a new Smatch warning:

iio:adc:qcom-spmi-vadc: add default scale to LR_MUX2_BAT_ID channel

2021-03-24T10:07:35+00:00

commit 7d200b283aa049fcda0d43dd6e03e9e783d2799c upstream.

Checking at both msm8909-pm8916.dtsi and msm8916.dtsi from downstream
it is indicated that "batt_id" channel has to be scaled with the default
function:

	chan@31 {
		label = "batt_id";
		reg = <0x31>;
		qcom,decimation = <0>;
		qcom,pre-div-channel-scaling = <0>;
		qcom,calibration-type = "ratiometric";
		qcom,scale-function = <0>;
		qcom,hw-settle-time = <0xb>;
		qcom,fast-avg-setup = <0>;
	};

Change LR_MUX2_BAT_ID scaling accordingly.
