This patch splits the current r8192e_pci driver up into six different
drivers: rtllib, rtllib_crypt, rtllib_crypt_ccmp, rtllib_crypt_tkip,
rtllib_crypt_wep, and r8192e_pci.
Now that they are proper modules, the init and exit functions do not
need to be called directly. Also, the rtllib_*_null functions are not
needed since they will be loaded on demand.

The rtl8192e driver had a natural split between the more generic
rtllib code and the more specific rtl8192e code. This patch exports
all the symbols needed by the r8192 specific code from the rtllib
generic code.

The lis3l02dq_read_event_config() function returned an ssize_t up to
now, which lead to a compiler warning in line 660 (initialization from
incompatible pointer type). The iio_info struct is defined to accept an
int-returning function as the read_event_config parameter.
Also it seems odd to have the check for (ret < 0) and return ret in
this case, when the return type is signed.

The loop used to reset the interrupt masks has faulty logic. There are 4
banks of 8 I/O, however each mask is comprised of 2 bits and thus there are
8 sets of registers to clear. Driver was wrongly equating this with 8 banks
leading to a us writing past the end of the "bank" array (used to store mask
configuration as these registers are write only) and thus causing memory
corruption. Clear both registers of masks for each bank and half iterations.

The function ad7280_store_balance_timer() parses data from a char*
buffer into a long variable, but uses the the function strict_strtoul
which expects a pointer to an unsigned long variable as its third
parameter.
As Dan Carpenter mentioned, the values are capped a few lines later,
but a check if val is negative is missing.
Now this function will return -ERANGE if there is a representation of
a negative number in buf.
Additionally the checkpatch.pl considers strict_strtoul as obsolete.
I replaced its call with the suggested kstrtoul.

The code in sca3000_store_measurement_mode() uses the variable val to
do bitwise operations with an int mask and or-s it into st->rx[0] which
is an entry in a u8 array (see sca3000.h).
This means up to now values larger than a u8 were silently ignored and
just the lower 8 bits counted into the value that was written into
st->rx[0]. This code will return -ERANGE if the value in buf was too
large to fit into a u8.

In lis3102dq_write_frequency() we used a long variable to store the
value parsed from the char* buffer buf, as there only was a
strict_strtol() function to parse values.
Now we have got kstrto* which allows us to convert to the right data
type in most cases.
In this particular function we want to write a frequency value, and it
doesn't make sense to allow negative values here (as Dan Carpenter
pointed out in a previous email).
This means we can now parse the value into an unsigned long and get an
error for invalid (e.g. negative) values.

In the adis16220_write_16bit() function we used a long value to store
parsed data from the char* buffer buf.
The called function to actually write the data,
adis16220_spi_write_reg_16(), takes a u16 value as a parameter, so up
to now a value larger than u16 was silently ignored as it was only
truncated when passing the parameter.
Now this function will only accept values fitting into a u16.
Additionally the parsing function was changed to overcome the now
obsolete strict_strtol() function.

this is already checked by loop stopping conditional.
The side effect is reduced indentation depth
from:
if (!list_empty)
list_for_each()
to:
list_for_each()
2. drop cb_ prefix from cl_pos, cl_next variables used in list_for_each
