The `COMEDI_BUFINFO` ioctl is used to advance the current position in

command in the "read" direction.  If the command has already stopped
normally, and the "read" position has been advanced to the end of all
available data, the command is terminated by calling
`do_become_nonbusy()`.  (That is not currently done if the command
stopped with an error.)  Currently, the command is only terminated if
the user is trying to advance the "read" position by a non-zero amount.
Change it to allow the command to be terminated even if the user is not
trying to advance the "read" position.  This is justifiable, as the only
time a command stops without error is when it has been set up to read a

Advancing the "write" position is current done even if the command has

The `COMEDI_BUFINFO` ioctl is used to advance the current position in
the buffer by a specified amount (which can be 0) and get the new
position.  On input, the `bytes_read` member of `struct comedi_bufinfo`
specifies the amount to advance the "read" position for an asynchronous
command in the "read" direction, and the `bytes_written` member

the updated position information, along with the adjusted `bytes_read`
and `bytes_written` members.

Advancing the buffer position occurs in two steps: first, some buffer
space is allocated, and second, it is freed, advancing the current
"read" or "write" position.  Currently, `do_bufinfo_ioctl()` limits
`bytes_read` or `bytes_written` to the amount it could allocate in the
first step, but that is invisible and irrelevant to the ioctl user.
It's mostly irrelevant to the COMEDI internals as well, apart from
limiting how much can be freed in the second step.  Change it to ignore
how much it managed to allocate in the first step and just use the
amount that was actually freed in the second step, which is the amount
the current buffer position was actually moved by this ioctl call.

staging: rtl8712: reduce stack usage

The "translate_scan" function in rtl8712 uses a lot of stack, and
gets inlined into its single caller, r8711_wx_get_scan, which
in some configurations now blows the 1024 byte stack warning
limit:

drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'r8711_wx_get_scan':
drivers/staging/rtl8712/rtl871x_ioctl_linux.c:1227:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

This somewhat reduces the stack usage by moving the translate_scan
function out of line with the noinline_for_stack annotation.
It might be possible to modify translate_scan() a little further
to reduce the stack usage, but with this patch, we can build without
the warning, the the call chain to get here is rather predictable
(sys_ioctl->vfs_ioctl->sock_ioctl->dev_ioctl->wext_ioctl->
r8711_wx_get_scan).
