rtw_read8() reads data from device via USB API which may fail. In case
of any failure previous code returned stack data to callers, which is
wrong.
Fix it by changing rtw_read8() prototype and prevent caller from
touching random stack data

The commit eecb3e4e5d9d ("staging: olpc_dcon: add OLPC display controller
(DCON) support") added this driver in 2010, and has been in staging since
then. It was marked as broken at some point because it didn't even build
but that got removed once the build issues were addressed.
But it seems that the work to move this driver out of staging has stalled,
the last non-trivial change to fix one of the items mentioned in its todo
file was commit e40219d5e4b2 ("staging: olpc_dcon: allow simultaneous XO-1
and XO-1.5 support") in 2019.
And even if work to destage the driver is resumed, the fbdev subsystem has
been deprecated for a long time and instead it should be ported to DRM.
Now this driver is preventing to land a kernel wide change, that makes the
num_registered_fb symbol to be private to the fbmem.c file.
So let's just mark the driver as broken. Someone can then work on making
it not depend on the num_registered_fb symbol, allowing to drop the broken
dependency again.

backlight_properties.fb_blank is deprecated. The states it represents
are handled by other properties; but instead of accessing those

Instead of manually checking the power state in struct

Commit 40867d74c374 ("net: Add l3mdev index to flow struct and avoid oif
reset for port devices") adds a new entry (flowi_l3mdev) in the common
flow struct used for indicating the l3mdev index for later rule and
table matching.
The l3mdev_update_flow() has been adapted to properly set the
flowi_l3mdev based on the flowi_oif/flowi_iif. In fact, when a valid
flowi_iif is supplied to the l3mdev_update_flow(), this function can
update the flowi_l3mdev entry only if it has not yet been set (i.e., the
flowi_l3mdev entry is equal to 0).
The SRv6 End.DT6 behavior in VRF mode leverages a VRF device in order to
force the routing lookup into the associated routing table. This routing
operation is performed by seg6_lookup_any_nextop() preparing a flowi6
data structure used by ip6_route_input_lookup() which, in turn,
(indirectly) invokes l3mdev_update_flow().
However, seg6_lookup_any_nexthop() does not initialize the new
flowi_l3mdev entry which is filled with random garbage data. This
prevents l3mdev_update_flow() from properly updating the flowi_l3mdev
with the VRF index, and thus SRv6 End.DT6 (VRF mode)/DT46 behaviors are
broken.
This patch correctly initializes the flowi6 instance allocated and used
by seg6_lookup_any_nexhtop(). Specifically, the entire flowi6 instance
is wiped out: in case new entries are added to flowi/flowi6 (as happened
with the flowi_l3mdev entry), we should no longer have incorrectly
initialized values. As a result of this operation, the value of
flowi_l3mdev is also set to 0.
The proposed fix can be tested easily. Starting from the commit
referenced in the Fixes, selftests [1],[2] indicate that the SRv6
End.DT6 (VRF mode)/DT46 behaviors no longer work correctly. By applying
this patch, those behaviors are back to work properly again.

2. Prevent unnecessary warnings regarding rate limiting support.-

nfp_net_sriov_check is added in nfp_app_get_vf_config which intends
to ensure ivi->vlan_proto and ivi->max_tx_rate/min_tx_rate can be
read from VF config table only when firmware supports corresponding
capability.
However, "nfp_app_get_vf_config" can be called by commands like
"ip a", "ip link set $DEV up" and "ip link set $DEV vf $NUM vlan
$param" (with VF). When using commands above, many warnings
"ndo_set_vf_<cap_x> not supported" would appear if firmware doesn't
support VF rate limit and 802.1ad VLAN assingment. If more VFs are
created, things could get worse.
Thus, this patch add an extra bool parameter for nfp_net_sriov_check
to enable/disable the cap check warning report. Unnecessary warnings
in nfp_app_get_vf_config can be avoided. Valid warnings in kinds of
vf setting function can be reserved.

cros_ec_get_host_event_wake_mask() expects to receive
sizeof(struct ec_response_host_event_mask) from send_command(). The
payload is valid only if the return value is positive.
Return -EPROTO if send_command() returns 0 in
cros_ec_get_host_event_wake_mask().

cros_ec_get_host_event_wake_mask() expects to receive
sizeof(struct ec_response_host_event_mask) from send_command().
The payload is valid only if the return value is positive.
Add Kunit tests for returning 0 from send_command() in
cros_ec_get_host_event_wake_mask().

cros_ec_get_host_event_wake_mask() used to return value from
send_command() which is number of bytes for input payload on success
(i.e. sizeof(struct ec_response_host_event_mask)).
However, the callers don't need to know how many bytes are available.
Don't return number of available bytes. Instead, return 0 on success;
otherwise, negative integers on error.
