If memdup_user() fails then "pparmbuf" is an error pointer and we can't
pass it to kfree(). I changed the "goto _r871x_mp_ioctl_hdl_exit" to a
direct return.
I changed the earlier goto to a direct return as well for consistency
and removed the "pparmbuf = NULL" initializer since it's no longer
needed.

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:

expression E;
identifier V;

- V = (T) _malloc(E);
+ V = kmalloc(E, GFP_ATOMIC);

struct was changed. For strong signals, this change made no difference;
however for medium and weak signals it results in a low signal that
shows considerable fluctuation, When using wicd for a medium-strength
AP, the value reported in the status line is reduced from 100% to 60% by

The ioctl handlers were frequently returning -1 upon failure. Most of
these have now been changed to proper errno macros.
The few remaining ones have been left untouched because either the
handler is not called (and so cannot be tested), or the function never
fails (and so cannot be system-tested), or requires new code to
distinguish its failures.

The original Realtek code assumed that ioctl Sets get done after the
interface is Up. This included the set to Essid and to the AP MAC#;
and it fit Realtek's installation procedure. But there is no such
necessity for the adapter, and no stated requirement found
elsewhere. Also, wireless drivers typically permit this.
A typical error message used to be:
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device wlan0 ; Operation not permitted.
