Staging: rtl8192e: Use ether_addr_copy() instead of memcpy()

This patch replaces memcpy with ether_addr_copy.
Also pathole was used to make sure that arguments passed to ether_addr_copy
are aligned to u16.
First argument is iwe.u.ap_addr.sa_data i output of pahole is:
struct iw_event {
__u16                      len;                  /*     0     2 */

/* sum members: 20, holes: 1, sum holes: 4 */
/* last cacheline: 24 bytes */
};
and inside union iwreq_data u is sa_data:
struct sockaddr {
/* typedef sa_family_t -> __kernel_sa_family_t */ short unsigned int sa_family; /*     8     2 */
char       sa_data[14];                                          /*    10    14 */

sa_data is a char array of size 14, and the number of bytes copied using
ether_addr_copy() is 6.

staging: unisys: Rework Kconfig dependencies

I find the Kconfig dependencies of the various Unisys drivers rather
confusing. Due to the dependencies, you must select the drivers one by
one to see the following ones. So if you are looking for a specific
driver, it is not visible by default. And if you don't know exactly
what you need, it's even worse as you don't know what is available.

In a case like this with several helper drivers and many dependencies,
I think it makes more sense to list all the drivers at first, and use
select statements to fulfill the dependencies for the user.

As a nice side effect, it avoids the weird indentation, which was
technically correct but still somewhat confusing.

I also dropped the dependencies on HAS_IOMEM, as the whole driver set
is for X86_64 only anyway which always has HAS_IOMEM set. And I
dropped the redundant dependencies on UNISYSSPAR as all drivers are
already inside an "if UNISYSSPAR" block.

Staging: rtl8192u: Replace printk() with pr_debug()

For dynamic debugging netdev_dbg(), dev_dbg() or  pr_debug() macro is
preferred over printk(), which is the raw way to print something.
Network system has it's own printk format, netdev_dbg, but in this case
function's argument list has no  pointer to a struct netdevice so
pr_debug is used instead.
