staging: comedi: drivers: move comedi_async 'cur_chan' tracking into the core

The commedi_async 'cur_chan' member is used to track the current position
in the chanlist for a scan. Currently only a couple comedi drivers use
this member.

For aeshtetics, move the 'cur_chan' tracking into the core for non-SDF_PACKED
subdevices. The 'cur_chan' will be updated after reading or writing samples
to the async buffer by comedi_inc_scan_progress(). All non-SDF_PACKED subdevices
will then automatiaclly track the 'cur_chan'.

Some of the drivers use the 'cur_chan' to detect the end of scan event when
counting scans. The COMEDI_CB_EOS event is automatically added by the core
when the end of scan is detected. The drivers just need to check if the
'cur_chan' is 0 to count the number of scans completed.

running on the subdevice, check that flag instead.

staging: comedi: maybe force CMDF_WRITE command flag

Most comedi subdevices that support asynchronous commands only support
data transfer in either the "read" or "write" direction, as indicated by
the `SDF_CMD_READ` and `SDF_CMD_WRITE` subdevice flags, although a few
support both directions on the same subdevice (though not
simultaneously).  The `struct comedi_cmd` structure passed via ioctl
call to set up the command contains a `CMDF_WRITE` flag that can be used
to choose the direction if the subdevice supports both directions, but
the flag is optional if the subdevice only supports data transfer in one
direction.

If the subdevice only supports asynchronous data transfer in a sing
direction, set the `CMDF_WRITE` flag to the correct state so that Comedi
can make use of it later.  In the case of the `COMEDI_CMDTEST` ioctl,
the updated flag will be written back to the `struct comedi_cmd` in
user-space.  In the case of the `COMEDI_CMD` ioctl, the flag only gets
written back if an error is detected while testing the command, or if
the `CMDF_BOGUS` command flag is set.  Since `__comedi_get_user_cmd()`
is called for both ioctls, that's a good place to set the flag.

Staging: lustre: lnet: Improve 'incarnation' stamp

ksock_net_t uses a __u64 quantity as an 'incarnation' timestamp. This is also
passed on in hello messages and used to detect if a reboot has occurred.
This 'incarnation' is obtained using do_gettimeofday.It is only used in equality
checks, so the absolute value does not matter.

This patch replaces do_gettimeofday with ktime_get_ns for the following reasons:
1. ktime_get_ns returns a __u64 which is safer than 'struct timeval'
which will overflow on 32-bit systems in year 2038 and beyond.
2. Reduced compute: ktime_get_ns is faster than the multiply/add
   combination used in this function

 "Three main MTD fixes for 3.18:

   - A regression from 3.16 which was noticed in 3.17.  With the
     restructuring of the m25p80.c driver and the SPI NOR library
     framework, we omitted proper listing of the SPI device IDs.  This
     means m25p80.c wouldn't auto-load (modprobe) properly when built as
     a module.  For now, we duplicate the device IDs into both modules.

   - The OMAP / ELM modules were depending on an implicit link ordering.
     Use deferred probing so that the new link order (in 3.18-rc) can
     still allow for successful probing.

irda: stop calling sk_prot->disconnect() on connection failure

The sk_prot is irda's own set of protocol handlers, so irda should
statically know what that function is anyway, without using an indirect
pointer.  And as it happens, we know *exactly* what that pointer is
statically: it's NULL, because irda doesn't define a disconnect
operation.

So calling that function is doubly wrong, and will just cause an oops.

drm/exynos: correct connector->dpms field before resuming

During system suspend after connector switch off its dpms field
is set to connector previous dpms state. To properly resume dpms field
should be set to its actual state (off) before resuming to previous dpms state.

drm/exynos: enable vblank after DPMS on

Before DPMS off driver disables vblank.
It should be balanced by vblank enable after DPMS on.
The patch fixes issue with page_flip ioctl not being able
to acquire vblank counter introduced by patch:

drm/exynos: init kms poll at the end of initialization

HPD events can be generated by components even if drm_dev is not fully
initialized, to skip such events kms poll initialization should
be performed at the end of load callback followed directly by forced
connection detection.
