specifies the amount to advance the "read" position for an asynchronous

the buffer. On output, the `struct comedi_bufinfo` is filled in with
the updated position information, along with the adjusted `bytes_read`

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

gets inlined into its single caller, r8711_wx_get_scan, which

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).
Fix a driver hang caused by earlier suspend/resume cycles. By handling a
ENODEV error during suspend as a real error we eventually end up stopping
the whole driver.
Fix this by handling the ENODEV error (during suspend) essentially by
retrying.
