f085bd4bfe USB: Fix ehci infinite suspend-resume loop issue in zhaoxin
In zhaoxin platform, some ehci projects will latch a wakeup signal
internal when plug in a device on port during system S0. This wakeup
signal will turn on when ehci runtime suspend, which will trigger a
system control interrupt that will resume ehci back to D0. As no
device connect, ehci will be set to runtime suspend and turn on the
internal latched wakeup signal again. It will cause a suspend-resume
loop and generate system control interrupt continuously.

Fixed this issue by clear wakeup signal latched in ehci internal when
ehci resume callback is called.

c14766a8a8 selftests/bpf: Fix map tests errno checks
Switching to libbpf 1.0 API broke test_lpm_map and test_lru_map as error
reporting changed. Instead of setting errno and returning -1 bpf calls
now return -Exxx directly.
Drop errno checks and look at return code directly.

6a12b8e20d selftests/bpf: Fix prog_tests uprobe_autoattach compilation error
I am getting the following compilation error for prog_tests/uprobe_autoattach.c:

  ./test_progs.h:209:26: error: pointer ‘mem’ may be used after ‘free’ [-Werror=use-after-free]

The value of mem is now used in one of the asserts, which is why it may be
confusing compilers. However, it is not dereferenced. Silence this by moving
free(mem) after the assert block.

There are few scenerio when PMC reports 'busy condition' and command
fail.

If PMC receives a high priority command while servicing a low priority
command then it discards the low priority command and start servicing
the high priority command. The lower priority command fail and driver
returns error. If the same command resend to the PMC then PMC latches
the command and service it accordingly.

Thus adds the retry logic for the PMC command.

7e842d70fe memory: renesas-rpc-if: Fix HF/OSPI data transfer in Manual Mode
HyperFlash devices fail to probe:

    rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed

In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits
(SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived
from half of the transfer size, cfr. the rpcif_bits_set() helper
function.  However, rpcif_reg_{read,write}() does not take the bus size
into account, and does not double all Manual Mode Data Register access
sizes when communicating with a HyperFlash or Octal-SPI Flash device.

Fix this, and avoid the back-and-forth conversion between transfer size
and Transfer Data Enable bits, by explicitly storing the transfer size
in struct rpcif, and using that value to determine access size in
rpcif_reg_{read,write}().

Enforce that the "high" Manual Mode Read/Write Data Registers
(SM[RW]DR1) are only used for 8-byte data accesses.
While at it, forbid writing to the Manual Mode Read Data Registers,
as they are read-only.

d09a7db431 ASoC: rsnd: care return value from rsnd_node_fixed_index()
Renesas Sound is very complex, and thus it needs to use
rsnd_node_fixed_index() to know enabled pin index.

It returns error if strange pin was selected,
but some codes didn't check it.

This patch 1) indicates error message, 2) check return
value.

9d87e41a6d i40e, xsk: Get rid of redundant 'fallthrough'
Intel drivers translate actions returned from XDP programs to their own
return codes that have the following mapping:

XDP_REDIRECT -> I40E_XDP_{REDIR,CONSUMED}
XDP_TX -> I40E_XDP_{TX,CONSUMED}
XDP_DROP -> I40E_XDP_CONSUMED
XDP_ABORTED -> I40E_XDP_CONSUMED
XDP_PASS -> I40E_XDP_PASS

Commit b8aef650e5 ("i40e, xsk: Terminate Rx side of NAPI when XSK Rx
queue gets full") introduced new translation

XDP_REDIRECT -> I40E_XDP_EXIT

which is set when XSK RQ gets full and to indicate that driver should
stop further Rx processing. This happens for unsuccessful
xdp_do_redirect() so it is valuable to call trace_xdp_exception() for
this case. In order to avoid I40E_XDP_EXIT -> IXGBE_XDP_CONSUMED
overwrite, XDP_DROP case was moved above which in turn made the
'fallthrough' that is in XDP_ABORTED useless as it became the last label
in the switch statement.

Simply drop this leftover.

42ba130807 bpf: Make btf_find_field more generic
Next commit introduces field type 'kptr' whose kind will not be struct,
but pointer, and it will not be limited to one offset, but multiple
ones. Make existing btf_find_struct_field and btf_find_datasec_var
functions amenable to use for finding kptrs in map value, by moving
spin_lock and timer specific checks into their own function.

The alignment, and name are checked before the function is called, so it
is the last point where we can skip field or return an error before the
next loop iteration happens. Size of the field and type is meant to be
checked inside the function.
