staging: vchiq_core: simplify vchiq_add_service_internal

Better use kzalloc to properly init vchiq_service with zero. As a result
this saves us all the zero assignments.

staging: vchiq_core: fix type of parameter localport

staging: r8188eu: handle rtw_init_netdev_name() failure appropriately

rtw_init_netdev_name() calls dev_alloc_name() which allocates the name
for the device as per the given name format.
The name format is specified by the module parameter "ifname".
It returns a negative err code if the format is invalid. Handle this
error appropriately.
Cancel the timers ininitliazed by rtw_init_drv_sw() before calling
rtw_free_drv_sw() and then proceed to free the adapter.

Also, if register_netdev() fails then goto free_drv_sw instead of
goto handle_dualmac.

staging: pi433: move get version func to where all other functions are

As a convention for the pi433 driver, all routines that deals with the
rf69 chip are defined in the rf69.c file. There was an exception to the
rule in which the uC version verification was being done directly
elsewhere. While at it, the Version Register hardcoded value was
replaced with a pre-existing constant in the driver.

This patch adds rf69_get_version function to rf69.c

This is because the compiler sees it is possible for "ptr" to be a NULL
value, and concludes that it has zero size and attempts to copy to it
would overflow. Instead, remove the get_recvframe_data() entirely, as
it's not possible for this to ever be NULL.

Additionally add missing NULL checks after recvframe_pull() (which are
present in the rtl8712 driver).

This is because the compiler sees it is possible for "ptr" to be a NULL
value, and concludes that it has zero size and attempts to copy to it
would overflow. Instead, remove the get_recvframe_data() entirely, as
it's not possible for this to ever be NULL.

Additionally add missing NULL checks after recvframe_pull() (which are
present in the rtl8712 driver).

staging: wfx: do not probe the device if not in the DT

Since the WF200 VID/PID are not reliable, it's recommended to declare it
in the DT. Until now, if the device was not declared, the driver just
printed a warning and continue. But, the risk of a collision is too
high, the driver now returns an error.

staging: wfx: rename "config-file" DT attribute

"config-file" is too broad. Replace it by "silabs,antenna-config-file"

The attribute "config-file" is probably not widely used. This patch

staging: wfx: map 'compatible' attribute with board name

"WF200" only designates the chip. To make a WiFi board, the chip must be
associated with an antenna. The antenna configuration is located in
separate files (aka PDS files in Silabs wording). Currently, user has to
write in his DT something like:

    compatible = "silabs,wf200";
    config = "brd4001a.pds";

It is far better to embed a list of known boards (chip + antenna) in the
driver. So the user just have to declare:

    compatible = "silabs,brd4001a";

This patch add the configurations for the evaluation boards sold by
Silabs. To provide a full plug-and-play experience, the associated PDS
files[1] will be available in linux-firmware.

This patch does not break compatibility with existing setups.
