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.

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,
written from scratch, rtl8xxxu driver to eventually gain
support for sdio devices. But there is no clear timeline
for that, so lets add this driver included in staging for now.

The final size of the buffer used for the streaming transfer consists of
the size for the user payload (buffer_size) and the size for the gaps
needed by the controller (extra_len).
The current implementation of the hdm_configure_channel() corrects the
buffer size down to the next appropriate for the hardware value, that is
the whole number of frames, but uses the old unaligned value to
calculate the extra_len.

When a channel is being removed while an application holds the
corresponding character device, this device is going to be destroyed only
after the application closes the file descriptor and releases character

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()

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.
