atm: nicstar: register the interrupt handler in the right place

Because the error handling is sequential, the application of resources
should be carried out in the order of error handling, so the operation
of registering the interrupt handler should be put in front, so as not
to free the unregistered interrupt handler during error handling.

atm: nicstar: use 'dma_free_coherent' instead of 'kfree'

When 'nicstar_init_one' fails, 'ns_init_card_error' will be executed for
error handling, but the correct memory free function should be used,
otherwise it will cause an error. Since 'card->rsq.org' and
'card->tsq.org' are allocated using 'dma_alloc_coherent' function, they
should be freed using 'dma_free_coherent'.

Fix this by using 'dma_free_coherent' instead of 'kfree'

atm: nicstar: Fix possible use-after-free in nicstar_cleanup()

This module's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.

Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

Merge drm/drm-next into drm-misc-next

Required backmerge since we will be based on top of v5.11, and there
has been a request to backmerge already to upstream some features.

Merge tag 'net-next-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- support "prefer busy polling" NAPI operation mode, where we defer
softirq for some time expecting applications to periodically busy
poll

- AF_XDP: improve efficiency by more batching and hindering the
adjacency cache prefetcher

- af_packet: make packet_fanout.arr size configurable up to 64K

- tcp: optimize TCP zero copy receive in presence of partial or
unaligned reads making zero copy a performance win for much smaller
messages

- XDP: add bulk APIs for returning / freeing frames

- sched: support fragmenting IP packets as they come out of conntrack

- net: allow virtual netdevs to forward UDP L4 and fraglist GSO skbs

BPF:

- BPF switch from crude rlimit-based to memcg-based memory accounting

- BPF type format information for kernel modules and related tracing
enhancements

- BPF implement task local storage for BPF LSM

- allow the FENTRY/FEXIT/RAW_TP tracing programs to use
bpf_sk_storage

Protocols:

- mptcp: improve multiple xmit streams support, memory accounting and
many smaller improvements

- TLS: support CHACHA20-POLY1305 cipher

- seg6: add support for SRv6 End.DT4/DT6 behavior

- sctp: Implement RFC 6951: UDP Encapsulation of SCTP

- ppp_generic: add ability to bridge channels directly

- bridge: Connectivity Fault Management (CFM) support as is defined
in IEEE 802.1Q section 12.14.

Drivers:

- mlx5: make use of the new auxiliary bus to organize the driver
internals

- mlx5: more accurate port TX timestamping support

- mlxsw:
- improve the efficiency of offloaded next hop updates by using
the new nexthop object API
- support blackhole nexthops
- support IEEE 802.1ad (Q-in-Q) bridging

- rtw88: major bluetooth co-existance improvements

- iwlwifi: support new 6 GHz frequency band

- ath11k: Fast Initial Link Setup (FILS)

- mt7915: dual band concurrent (DBDC) support

- net: ipa: add basic support for IPA v4.5

Refactor:

- a few pieces of in_interrupt() cleanup work from Sebastian Andrzej
Siewior

- phy: add support for shared interrupts; get rid of multiple driver
APIs and have the drivers write a full IRQ handler, slight growth
of driver code should be compensated by the simpler API which also
allows shared IRQs

- add common code for handling netdev per-cpu counters

- move TX packet re-allocation from Ethernet switch tag drivers to a
central place

- improve efficiency and rename nla_strlcpy

- number of W=1 warning cleanups as we now catch those in a patchwork
build bot

Old code removal:

- wan: delete the DLCI / SDLA drivers

- wimax: move to staging

- wifi: remove old WDS wifi bridging support"
