[ Upstream commit a5e5e03e94 ]
Internally kernel prepends all report buffers, for both numbered and
unnumbered reports, with report ID, therefore to properly handle unnumbered
reports we should prepend it ourselves.
For the same reason we should skip the first byte of the buffer when
calling i2c_hid_set_or_send_report() which then will take care of properly
formatting the transfer buffer based on its separate report ID argument
along with report payload.

Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
field initialization.
In htc_connect_service() svc_meta_len and pad are not initialized. Based
on code it looks like in current skb there is no service data, so simply
initialize svc_meta_len to 0.
htc_issue_send() does not initialize htc_frame_hdr::control array. Based
on firmware code, it will initialize it by itself, so simply zero whole
array to make KMSAN happy

[ Upstream commit 75478b3b39 ]
The current code, when parsing the EDID Deep Color depths, that the
YUV422 cannot be used, referring to the HDMI 1.3 Specification.
This specification, in its section 6.2.4, indeed states:
For each supported Deep Color mode, RGB 4:4:4 shall be supported and
optionally YCBCR 4:4:4 may be supported.
YCBCR 4:2:2 is not permitted for any Deep Color mode.
This indeed can be interpreted like the code does, but the HDMI 1.4
specification further clarifies that statement in its section 6.2.4:
For each supported Deep Color mode, RGB 4:4:4 shall be supported and
optionally YCBCR 4:4:4 may be supported.
YCBCR 4:2:2 is also 36-bit mode but does not require the further use
of the Deep Color modes described in section 6.5.2 and 6.5.3.
This means that, even though YUV422 can be used with 12 bit per color,
it shouldn't be treated as a deep color mode.
This is also broken with YUV444 if it's supported by the display, but
DRM_EDID_HDMI_DC_Y444 isn't set. In such a case, the code will clear
color_formats of the YUV444 support set previously in
drm_parse_cea_ext(), but will not set it back.
Since the formats supported are already setup properly in
drm_parse_cea_ext(), let's just remove the code modifying the formats in
drm_parse_hdmi_deep_color_info()

Consider that platform_get_irq() can now in certain cases return

convert that into -EINVAL, even at probe time rather than later on.

And it will cause refcount leak in error paths.
For example, when codec_np is NULL, saif_np[0] and saif_np[1]

of_node_put() will check if the node pointer is NULL, so we can

This code has two bugs:
1) "cnt" is 255 but the size of the buffer is 256 so the last byte is
not used.
2) If we try to print more than 255 characters then "cnt" will be
negative and that will trigger a WARN() in snprintf(). The fix for
this is to use scnprintf() instead of snprintf().
We can re-write this code to be cleaner:
1) Rename "offset" to "off" because that's shorter.
2) Get rid of the "cnt" variable and just use "size - off" directly.
3) Get rid of the "read" variable and just increment "off" directly.

This is clearly wrong as it may cause the SLEEPABLE flag to be
set when it shouldn't.

commit 92912b1751 upstream.
Writes to a Downstream Port's Slot Control register are PCIe hotplug
"commands." If the Port supports Command Completed events, software must
wait for a command to complete before writing to Slot Control again.
pcie_do_write_cmd() sets ctrl->cmd_busy when it writes to Slot Control. If
software notification is enabled, i.e., PCI_EXP_SLTCTL_HPIE and
PCI_EXP_SLTCTL_CCIE are set, ctrl->cmd_busy is cleared by pciehp_isr().
But when software notification is disabled, as it is when pcie_init()
powers off an empty slot, pcie_wait_cmd() uses pcie_poll_cmd() to poll for
command completion, and it neglects to clear ctrl->cmd_busy, which leads to
spurious timeouts:
pcieport 0000:00:03.0: pciehp: Timeout on hotplug command 0x01c0 (issued 2264 msec ago)
pcieport 0000:00:03.0: pciehp: Timeout on hotplug command 0x05c0 (issued 2288 msec ago)
Clear ctrl->cmd_busy in pcie_poll_cmd() when it detects a Command Completed
event (PCI_EXP_SLTSTA_CC).

commit 244eae91a9 upstream.
Recent tightening of the opcode table in binutils so as to consistently
disallow the assembly or disassembly of CP0 instructions not supported
by the processor architecture chosen has caused a regression like below:
arch/mips/dec/prom/locore.S: Assembler messages:
arch/mips/dec/prom/locore.S:29: Error: opcode not supported on this processor: r4600 (mips3) `rfe'
in a piece of code used to probe for memory with PMAX DECstation models,
which have non-REX firmware. Those computers always have an R2000 CPU
and consequently the exception handler used in memory probing uses the
RFE instruction, which those processors use.
While adding 64-bit support this code was correctly excluded for 64-bit
configurations, however it should have also been excluded for irrelevant
32-bit configurations. Do this now then, and only enable PMAX memory
probing for R3k systems.

commit a5359ddd05 upstream.
GCC 10+ defaults to -fno-common, which enforces proper declaration of
external references using "extern". without this change a link would
fail with:
lib/raid6/test/algos.c:28: multiple definition of `raid6_call';
lib/raid6/test/test.c:22: first defined here
the pq.h header that is included already includes an extern declaration
so we can just remove the redundant one here.
