->KeyMaterial is declared as a 16 byte array, but we only ever allocate
either 5 or 13 bytes of it. The problem is that we memset() all 16
bytes to zero so we're memsetting past the end of the allocated memory.
I fixed this in slightly lazy way, by just allocating 16 bytes. This
works but there is a lot more cleanup you could do to this code if you
wanted. Which is why this code is in staging.

Use memdup_user() to avoid its duplicated implementation and simplify

which is valid because copy_from_user() might sleep and it's useless
to make the allocation atomic. Found with coccinelle.

This patch removes all usage of _malloc() and the function itself. Most
uses are straightforward replacements by kmalloc(..., GFP_ATOMIC),
because this was the definition of _malloc(). In a few places it
was possible to use kzalloc() or memdup_user.
A further improvement would be to replace GFP_ATOMIC with GFP_KERNEL
where possible.
Verified by compilation only.
Initial replacement done by running a Coccinelle script along the lines
of:
@@
type T;
expression E;
identifier V;
@@
- V = (T) _malloc(E);
+ V = kmalloc(E, GFP_ATOMIC);
@@
expression E, E1;
@@
- E1 = _malloc(E);
+ E1 = kmalloc(E, GFP_ATOMIC);

This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.
Verified by compilation only.

type T;
constant C;
identifier ret;

- T ret = C;

Fix potential leaks in the error paths of r8712_set_key(). In case the
algorithm specific checks fail, the function returns without enqueuing
or freeing the already allocated command and parameter structs. Use a
centralized exit path and make sure that all memory is freed correctly.

Fix a potential leak in the error path of r871x_wx_set_enc_ext(). In case the
requested algorithm is not supported by the driver, the function returns
without freeing the already allocated 'param' struct. Move the input
verification to the beginning of the function so that the direct return is
safe. Detected by Coverity - CID 144373.

Testing for "if (IS_ERR(padapter->cmdThread) < 0)" doesn't make sense.
The kthread_run() function returns error pointers on error pointers on
error so it should just be "if (IS_ERR(padapter->cmdThread))".

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
