the right value, notifies the hardware that the command is

The "verb" field should be the last one to be written in the
swp command registers, after all other fields are filled in.
The current implementation doesn't follow this rule for all

command being processed by the hardware. Enforce the correct

staging: wilc1000: Fix problem with wrong vif index

The vif->idx value is always 0 for two interfaces.

wl->vif_num = 0;

loop {
     ...

     vif->idx = wl->vif_num;
     ...
     wl->vif_num = i;
      ....
     i++;
     ...
}

At present, vif->idx is assigned the value of wl->vif_num
at the beginning of this block and device is initialized
based on this index value.
In the next iteration, wl->vif_num is still 0 as it is only updated
later but gets assigned to vif->idx in the beginning. This causes problems
later when we try to reference a particular interface and also while
configuring the firmware.

This patch moves the assignment to vif->idx from the beginning
of the block to after wl->vif_num is updated with latest value of i.

staging: comedi: labpc: fix isadma dependency

When COMEDI_NI_LABPC is built-in and COMEDI_NI_LABPC_ISA is a loadable
module, thhe ISA DMA code is not reachable by the common module, causing
a link error:

drivers/staging/built-in.o: In function `labpc_interrupt':
ni_labpc_common.c:(.text+0x1d178): undefined reference to `labpc_handle_dma_status'
ni_labpc_common.c:(.text+0x1d1cb): undefined reference to `labpc_drain_dma'
drivers/staging/built-in.o: In function `labpc_ai_cmd':
ni_labpc_common.c:(.text+0x1d8ad): undefined reference to `labpc_setup_dma'

This changes the definition of COMEDI_NI_LABPC_ISADMA so that it will
also be builtin for that case. This looks like a rather old bug, but
I have never seen this in randconfig testing until today.

staging: Add rtl8723bs sdio wifi driver

The rtl8723bs is found on quite a few systems used by Linux users,
such as on Atom systems (Intel Computestick and various other
Atom based devices) and on many (budget) ARM boards such as
the CHIP.

The plan moving forward with this is for the new clean,

support for sdio devices. But there is no clear timeline
for that, so lets add this driver included in staging for now.

needed by the controller (extra_len).

iio: imu: st_lsm6dsx: do not apply ODR configuration in write_raw handler

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()

iio: adc: sun4i: add THERMAL dependency

With CONFIG_THERMAL=m and CONFIG_SUN4I_GPADC=y, we get a link error
from calling devm_thermal_zone_of_sensor_register:

drivers/iio/built-in.o: In function `sun4i_gpadc_probe':
:(.text+0x1c284): undefined reference to `devm_thermal_zone_of_sensor_register'

This adds a Kconfig dependency to ensure we can only have the ADC
driver as built-in when this function is also built-in, or when
we see the empty stub implementation. When the thermal code is
a module, we can still build the adc driver as a module, too.

iio:imu:mpu6050 add explicit mpu9250 support

The mpu9250 is a SIP containing an mpu6500 and an ak8975.  If this was all
there was too it there would be no need for explicit handling in the driver.
Arguably the bindings would also only reflect the presence of an mpu6500 with
the ak8975 hanging off it, as the kernel doesn't care that they are in one
package.

However, the WHOAMI value changes as well so best to add explicit support.

iio: adc: cpcap: Add minimal support for CPCAP PMIC ADC

On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
has ADCs that are used for battery charging and USB PHY VBUS and ID pin
detection.

Unfortunately the only documentation for this ADC seems to be the
Motorola mapphone Linux kernel tree. I have tested that reading raw and
scaled values works, but I have not used the timed sampling that the ADC
seems to support.

Let's add a minimal support for it so we can eventually provide IIO
channels for the related battery charging and USB PHY drivers.
