R-Car LVDS encoder fix

[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.
This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.
[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

We need to set certain power gating flags after we determine
if the firmware version is sufficient to support gfxoff.
Previously we set the pg flags in early init, but we later
we might have disabled gfxoff if the firmware versions didn't
support it. Move adding the additional pg flags after we
determine whether or not to support gfxoff.

In certain cases when the probe function fails the error path calls
cpsw_remove_dt() before calling platform_set_drvdata(). This is an
issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the
cpsw_common data and leds to a NULL pointer exception. This patches
fixes it by calling platform_set_drvdata() earlier in the probe.

test_cgroup_storage fails on s390 with an assertion failure: packets are
dropped when they shouldn't. The problem is that BPF_DW packet count is
accessed as BPF_W with an offset of 0, which is not correct on

Since the point of this test is not to verify narrow loads/stores,
simply use BPF_DW when working with packet counts.

strict module rwx
We should keep the case of "#define debug_align(X) (X)" for all arches
without CONFIG_HAS_STRICT_MODULE_RWX ability, which would save people, who
are sensitive to system size, a lot of memory when using modules,
especially for embedded systems. This is also the intention of the
original #ifdef... statement and still valid for now.
Note that this still keeps the effect of the fix of the following commit,
38f054d549a8 ("modules: always page-align module section allocations"),
since when CONFIG_ARCH_HAS_STRICT_MODULE_RWX is enabled, module pages are
aligned.

This reverts commit 96cce12ff6e0 ("cfg80211: fix processing world
regdomain when non modular").
Re-triggering a reg_process_hint with the last request on all events,
can make the regulatory domain fail in case of multiple WiFi modules. On
slower boards (espacially with mdev), enumeration of the WiFi modules
can end up in an intersected regulatory domain, and user cannot set it
with 'iw reg set' anymore.
This is happening, because:
- 1st module enumerates, queues up a regulatory request
- request gets processed by __reg_process_hint_driver():
- checks if previous was set by CORE -> yes
- checks if regulator domain changed -> yes, from '00' to e.g. 'US'
-> sends request to the 'crda'
- 2nd module enumerates, queues up a regulator request (which triggers
the reg_todo() work)
- reg_todo() -> reg_process_pending_hints() sees, that the last request
is not processed yet, so it tries to process it again.
__reg_process_hint driver() will run again, and:
- checks if the last request's initiator was the core -> no, it was
the driver (1st WiFi module)
- checks, if the previous initiator was the driver -> yes
- checks if the regulator domain changed -> yes, it was '00' (set by
core, and crda call did not return yet), and should be changed to 'US'
------> __reg_process_hint_driver calls an intersect
Besides, the reg_process_hint call with the last request is meaningless
since the crda call has a timeout work. If that timeout expires, the
first module's request will lost.

Fix two shortcomings in the Extended Key ID API:
1) Allow the userspace to install pairwise keys using keyid 1 without
NL80211_KEY_NO_TX set. This allows the userspace to install and
activate pairwise keys with keyid 1 in the same way as for keyid 0,
simplifying the API usage for e.g. FILS and FT key installs.
2) IEEE 802.11 - 2016 restricts Extended Key ID usage to CCMP/GCMP
ciphers in IEEE 802.11 - 2016 "9.4.2.25.4 RSN capabilities".
Enforce that when installing a key.

The quirk function snd_emuusb_set_samplerate() has a NULL check for
the mixer element, but this is useless in the current code. It used
to be a check against mixer->id_elems[unitid] but it was changed later
to the value after mixer_eleme_list_to_info() which is always non-NULL
due to the container_of() usage.
This patch fixes the check before the conversion.
While we're at it, correct a typo in the comment in the function,
too.

Currently, we are only explicitly setting SOCK_NOSPACE on a write timeout
for non-blocking sockets. Epoll() edge-trigger mode relies on SOCK_NOSPACE
being set when -EAGAIN is returned to ensure that EPOLLOUT is raised.
Expand the setting of SOCK_NOSPACE to non-blocking sockets as well that can
use SO_SNDTIMEO to adjust their write timeout. This mirrors the behavior

In fault_opcodes_write(), 'data' is allocated through kcalloc(). However,
it is not deallocated in the following execution if an error occurs,
leading to memory leaks. To fix this issue, introduce the 'free_data' label
to free 'data' before returning the error.

In mlx4_ib_alloc_pv_bufs(), 'tun_qp->tx_ring' is allocated through
kcalloc(). However, it is not always deallocated in the following execution
if an error occurs, leading to memory leaks. To fix this issue, free
'tun_qp->tx_ring' whenever an error occurs.
