nes_unregister_ofa_device() dereferences the nesibdev pointer before
testing if it's NULL. Also, the test is doubly redundant because the
only caller of nes_unregister_ofa_device() is nes_destroy_ofa_device(),
which already tests if nesibdev is NULL. Remove the unnecessary test.
This was spotted by the Coverity checker (CID 2190).

Christoph Hellwig wants to unexport get_empty_filp(), which is an ugly
internal interface. Change the modular user in ib_uverbs_alloc_event_file()
to use the better alloc_file() interface; this makes the code cleaner too.
Signed-off-by: Roland Dreier <rolandd@cisco.com>
The file member of struct ib_uverbs_event_file was only used to keep
track of whether the file had been closed or not. The only thing we
ever did with the value was check if it was NULL or not. Simplify the
code and get rid of the need to keep track of the struct file * we
allocate by replacing the file member with an is_closed member.

The struct mlx4_interface.event() method was supposed to get an enum
mlx4_dev_event, but the driver code was actually passing in the
hardware enum mlx4_event values. Fix up the callers of
mlx4_dispatch_event() so that they pass in the right type of value,
and fix up the event method in mlx4_ib so that it can handle the enum
mlx4_dev_event values.
This eliminates the need for the subtype parameter to the event
method, so remove it.
This also fixes the sparse warning

This patch is a largely cosmetic cleanup of the TIPC reference
table code.
- The object reference field in each table entry is now single
32-bit integer instead of a union of two 32-bit integers.
- Variable naming has been made more consistent.
- Error message output has been made more consistent.
- Useless #includes have been eliminated.

drivers/net/sb1000.c has lots of inlined static functions.
Mst of them are used at initialization, wait for some
hardware register to change (wait using yield, sleep etc),
or do slow port-based I/O. Inlining thse "for speed" makes no sense.
This patch removes "inline" from biggest static function
(regardless of number of callsites - gcc nowadays auto-inlines
statics with one callsite).

Problem: A STARTLAN command from the adapter may arrive while a
qeth recovery is currently running with a failed qeth
STARTLAN. Usually qeth schedules a recovery when
receiving a STARTLAN command from the adapter. But
another recovery scheduled while a recovery is already
running never starts. Thus the qeth-administered
lan_online flag remains zero in this scenario, even
though the adapter-STARTLAN has happened.
Solution: Set lan_online flag for a received STARTLAN from the
adapter in case scheduled recovery does not start.

2. ip_list handling after deregister failure or normal ip address:
If error code "IP Address not found" is returned do not re-add
multicast address to ip list.
This is especially important in IP address takeover scenarios,

winbond-840 shares tulip.h with the tulip driver, because they share
many (but not all) of the same register definitions.
This is useful for the register definitions, but not helpful when it
comes to symbols that are shared among the tulip driver's C modules,
but not meant to be shared outside that one driver.
Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding
upon a similar symbol in winbond-840's namespace. This was not a
problem as long as the two symbols had the same value, but upcoming
patches result in differing symbol values.
