staging: comedi: pcl726: fix the analog output range_table_list initialization
The analog output channels use jumpers on the board to individually set
the range used. This driver uses the configuration options passed to the
(*attach) function to setup the analog output subdevice range_table_list
for each channel.
The configuration options should be 'it->options[2 + i]' for each channel 'i'
not '...[2 + 1]' for each channel. Fix the error and move the code so that
the range_table_list is setup before the subdevice is initialized.

The offset binary value from the core should be saved for read back.
Move the saving of the value in the private data so it occurs before
the value is possibly munged for bipolar outputs.
Use the comedi_offset_munge() helper to munge the offset binary value
to two's complement for bipolar outputs.
According to the November 2011 users manual, the write order must be
MSB them LSB. Update the comment.
Modify the register map defines to handle the channel offset calculation.

These flags are set in the private data during the attach to indicate
if the range for each channel is bipolar or unipolar. Use the helper
function conedi_chan_range_is_bipolar() to determine this by checking
the range_table_list directly.

staging: usbip: Fix man-pages for usbip userspace utilities
The usbip userspace utilities contained some half-documented (only in
--help, not in man) options. They were added to the man-pages of usbip
and usbipd.
Also a typo in the usbip headline was fixed.
This patch removes dm_gpio_change_rf_callback() because it is not called
anywhere and it resides inside an #ifdef RTL8192E guard while RTL8192E
is not defined.
The function cmpk_message_handle_tx() is called only in r8192U_dm.c in two
places. The first call resides outside an #ifdef RTL8192U guard, and since
RTL8192U is defined this call can be removed. At the other site this function
is called, there is no check on its return value. Since cmpk_message_handle_tx()
does not do anything else other than returning true, it can be safely removed.
staging: rtl8192u: remove unused code from cmpk_message_handle_tx()
The file r819xU_cmdpkt.c includes header r8192U.h which defines RTL8192U.
This patch removes from cmpk_message_handle_tx() the part of the code that
is never used because it resides outside the header guard #ifdef RTL8192U.

staging: dwc2: add microframe scheduler from downstream Pi kernel
The transfer scheduler in the dwc2 driver is pretty basic, not to
mention buggy. It works fairly well with just a couple of devices
plugged in, but if you add, say, multiple devices with periodic
endpoints, the scheduler breaks down and can't even enumerate all
the devices.
To improve this, import the "microframe scheduler" patch from the
driver in the downstream Raspberry Pi kernel, which is based on
the Synopsys vendor driver. The original patch came from Denx
(http://git.denx.de/?p=linux-denx.git) and was commited to the
raspberrypi.org git tree by "popcornmix" (Dom Cobley).
I have added a driver parameter for this, enabled by default, in
case anyone has problems with it and needs to disable it. I don't
think we should add a DT binding for that, though, since I plan
to remove the option once any bugs are fixed.

staging: usbip: Fix IPv6 support in usbipd
getaddrinfo() leaves the order of the returned addrinfo structs
unspecified. On systems with bindv6only disabled (this is the default),
PF_INET6 sockets bind to IPv4, too. Thus, IPv6 support in usbipd was
broken when getaddrinfo returned first IPv4 and then IPv6 addrinfos, as
the IPv6 bind failed with EADDRINUSE.
This patch uses seperate sockets for IPv4 and IPv6 and sets IPV6_V6ONLY
on all IPv6 sockets. Two command line arguments, -4 and -6 were added to
manually select the socket family.

Normally, the macros from command line are system specific macros (e.g
__linux, __KERNEL__ ...), and module own macros are usually defined in
their header files.
DG_NAME and DG_PART are driver 'dgap' owned macros which are used by
multiple files within driver, and need be defined in the driver main
header file.
So move DG_NAME and DG_PART to "dgap_driver.h", it not only can make

staging: comedi: pcl711: no need to calc the timer values twice
The comedi core always calls the (*do_cmdtest) function to validate
a command before it calls the (*do_cmd) function.
Since the (*do_cmdtest) has already calculated the timer values in
order to validate the cmd->scan_begin_arg there is no reason to
recalc the values in the (*do_cmd).
This also fixes a bug in the driver. The (*do_cmdtest) was using a
time base value of 100 and but the (*do_cmd) was using a time base
of 500. These result in different timer values. The functions used
to calculate the values are actually the same due to a #define in
the 8253.h header.
