61241d97db drivers/staging: delete double assignment
Delete successive assignments to the same location.  In three of the cases,
the two assignments are identical.  In the case of the file
rt2860/common/cmm_aes.c, the assigned variable i is never used, so both
assignments are dropped.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>

fcbf77bf87 Staging: ft1000-usb: fix array overflow
The code here is supposed checking if we exited the loop without hitting
a break.  The problem is that in the error handling "i" is out of bounds
and it corrupts memory when we do an info->app_info[i].nRxMsgMiss++.
>From the comments, it looks like someone noticed this corruption and
updated the code, but didn't totally fix the problem.  The correct fix
is just to remove nRxMsgMiss++ from the error path.

I believe this bug can be triggered remotely.

2a953cfd42 staging/ft1000-usb: fix problems found by sparse
In the original code, address space annotations are missing,
which hides a possible unchecked user pointer access.

Two functions use a lot of stack space.

Extern declarations are all in the wrong place, which leads
to type differences between caller and callee in some cases.

7cfd8a3720 staging/ft1000-usb: fix build warnings
This lets us see clearer when stuff breaks.

Most of the changes are fixes for casts between int and pointer
that don't work on 64 bit.

The ioctl function uses a large amount of stack, which gets
fixed by allocating the buffer dynamically.

d16044cf8c staging: make new character devices nonseekable
As a preparation for changing the default behaviour of llseek to no_llseek,
every file_operations structure should have a .llseek operation.

There are three new instances in staging now, which can all be changed
into no_llseek explicitly since the devices do not need to seek.

Add nonseekable_open where appropriate, to prevent pread/pwrite as well.
