The IIO subsystem is redefining iio_dev->mlock to be used by
the IIO core only for protecting device operating mode changes.
ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes.
In this driver, mlock was being used to protect hardware state
changes. Replace it with a driver private lock.
Also, as there are state changes in the ad7192_ write_raw function, a lock
is added to prevent the concurrent state changes.

Platform devices are expected to use wrapper functions,
platform_{get,set}_drvdata() with platform_device as argument,
for getting and setting the driver data. dev_{get,set}_drvdata()
are using &plat_dev->dev.
For wrapper functions we can directly pass a struct platform_device.
dev_set_drvdata() is redundant and therefore removed. The driver core
clears the driver data to NULL after device_release or on probe failure.

If 'rtl8192_usb_initendpoints()' fails, it may have allocated some
resources that need to be freed. The corresponding is propagated up to
'rtl8192_usb_prob()'. So, in this function if an error
code is returned by 'rtl8192_init()' we should call
'rtl8192_usb_deleteendpoints()'.
Some error handling code is also duplicated in 'rtl8192_init()' and in
'rtl8192_usb_prob()'. This looks harmless because the freed pointers are
set to NULL but it looks confusing.
Fix all that by just moving the 'fail' label and removing duplicated
error handling code from 'rtl8192_ini()'. All this resources freeing will
be handled by 'rtl8192_usb_prob()' directly.
The calling graph is:
rtl8192_usb_probe
--> rtl8192_init
--> rtl8192_usb_initendpoints

If one of these memory allocations fail, a NULL pointer dereference will
occur later on.
Return -ENOMEM instead.
There is no need to free the resources already allocated, this is done
by the caller (i.e. 'rtl8192_usb_probe()') which calls
'rtl8192_usb_deleteendpoints()'.
