staging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN
If the "comedi" module has been loaded with the
"comedi_num_legacy_minors" module parameter set to a non-zero value,
some reserved comedi devices get created. These can be attached to a
low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
which checks for the `CAP_SYS_ADMIN` capability. Of course, the comedi
device needs to be opened before the ioctl command can be sent. If the
comedi device is unattached, `comedi_open()` currently requires the
`CAP_NET_ADMIN` capability. It makes more sense to just require the
`CAP_SYS_ADMIN` capability here, so change it.
For the curious, commit
a8f80e8ff94e ("Networking: use CAP_NET_ADMIN
when deciding to call request_module") changed this capability from
`CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
relevant here. The original `CAP_SYS_MODULE` capability was due to the
function having some code to request a module using a "char-major-%i-%i"
alias, but that was never compiled in and was removed by commit
f30f2c2d417b ("staging: comedi: remove check for CONFIG_KMOD").

staging: comedi: cb_pcimdas: add external analog output ranges
The analog output range is not programmable, but the ranges for each of
the two analog output channels are settable via jumpers. These jumper
settings are not readable by the driver. The driver
provides a range table containing all the possible internal ranges
(+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
application (although any range selected by the application that differs
from the jumper settings will not produce the expected voltage output).
The range table does not cover all possible ranges of the analog output
channels. The jumpers also allow an external reference voltage between
0 and 10V to be used as bipolar or unipolar output range. Add a couple
more ranges to the end of the range table to define these two external
ranges.

But what was going on was that the bluetooth code was using NULL
pointers for the list as a way to mark it empty, and that commit just
broke it (and replaced the test with NULL with a "list_empty()" test on
a uninitialized list instead, breaking things even further).
So fix it all up to use the regular and real list_empty() handling
(which does not use NULL, but a pointer to itself), also making sure to
initialize the list properly (the previous NULL case was initialized
implicitly by the session being allocated with kzalloc())
This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
An.

Merge branch 'for-next' of git://git./linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
"It's been a busy development cycle for target-core in a number of
different areas.
The fabric API usage for se_node_acl allocation is now within
target-core code, dropping the external API callers for all fabric
drivers tree-wide.
There is a new conversion to RCU hlists for se_node_acl and
se_portal_group LUN mappings, that turns fast-past LUN lookup into a
completely lockless code-path. It also removes the original
hard-coded limitation of 256 LUNs per fabric endpoint.
The configfs attributes for backends can now be shared between core
and driver code, allowing existing drivers to use common code while
still allowing flexibility for new backend provided attributes.
The highlights include:
- Merge sbc_verify_dif_* into common code (sagi)
- Remove iscsi-target support for obsolete IFMarker/OFMarker
(Christophe Vu-Brugier)
- Add bidi support in target/user backend (ilias + vangelis + agover)
- Move se_node_acl allocation into target-core code (hch)
- Add crc_t10dif_update common helper (akinobu + mkp)
- Handle target-core odd SGL mapping for data transfer memory
(akinobu)
- Move transport ID handling into target-core (hch)
- Move task tag into struct se_cmd + support 64-bit tags (bart)
- Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
paulmck)
- Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch +
paulmck)
- Simplify target backend driver registration (hch)
- Consolidate + simplify target backend attribute implementations
(hch + nab)
- Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch)
- Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab)
- Drop unnecessary core_tpg_register TFO parameter (nab)
- Use 64-bit LUNs tree-wide (hannes)
- Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)"

Pull NTB updates from Jon Mason:
"This includes a pretty significant reworking of the NTB core code, but
has already produced some significant performance improvements.
An abstraction layer was added to allow the hardware and clients to be
easily added. This required rewriting the NTB transport layer for
this abstraction layer. This modification will allow future "high
performance" NTB clients.
In addition to this change, a number of performance modifications were
added. These changes include NUMA enablement, using CPU memcpy
instead of asyncdma, and modification of NTB layer MTU size"

9p: cope with bogus responses from server in p9_client_{read,write}
if server claims to have written/read more than we'd told it to,
warn and cap the claimed byte count to avoid advancing more than
we are ready to.
