pcmcia_get_mac_from_cis is only called from networking and
recent changes made it call dev_addr_mod() which is itself
only defined if NET.

Fix the following fallthrough warning:

case 3:

drivers/pcmcia/db1xxx_ss.c:359:2: note: insert 'break;' to avoid fall-through
case 3:

This helps with the ongoing efforts to globally enable
-Wimplicit-fallthrough for Clang.

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

"Improve the use of the kobj API in the core of the Linux PCMCIA
subsystem"
* 'pcmcia-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
pcmcia: Switch to using the new API kobj_to_dev()
The driver core ignores the return value of struct device_driver::remove
because there is only little that can be done. To simplify the quest to
make this function return void, let struct sa1111_driver::remove return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea and ensures future
users behave accordingly.

The driver was introduced in 2.6.11 in the pre-git times with commit
"[PATCH] mips: vR41xx updates". However, even back then, this driver
was not able to be compiled, as a number of udpates had been missing
from this driver: It still provided a "->get_io_map" callback (removed
for v2.5.66) and a "->inquire_socket" callback and used socket_cap_t
(removed for v2.5.72). Moreover, this driver failed to be brought and
be kept up to date; e.g. it still provides '->register_callback',
incompatible with a change committed for v2.6.14 in
commit 7f316b033b ("[PATCH] pcmcia: remove socket register_callback"),
and uses INIT_WORK() with three arguments which was removed in
commit 65f27f3844 ("WorkStruct: Pass the work_struct pointer instead
of context data")

decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.
