2024-02-12ASoC: rt5645: Make LattePanda board DMI match more preciseHans de Goede
The DMI strings used for the LattePanda board DMI quirks are very generic. Using the dmidecode database from https://linux-hardware.org/ shows that the chosen DMI strings also match the following 2 laptops which also have a rt5645 codec: Insignia NS-P11W7100 https://linux-hardware.org/?computer=E092FFF8BA04 Insignia NS-P10W8100 https://linux-hardware.org/?computer=AFB6C0BF7934 All 4 hw revisions of the LattePanda board have "S70CR" in their BIOS version DMI strings: DF-BI-7-S70CR100-* DF-BI-7-S70CR110-* DF-BI-7-S70CR200-* LP-BS-7-S70CR700-* See e.g. https://linux-hardware.org/?computer=D98250A817C0 Add a partial (non exact) DMI match on this string to make the LattePanda board DMI match more precise to avoid false-positive matches.

2024-02-12net: sysfs: Fix /sys/class/net/<iface> path for statisticsBreno Leitao
The Documentation/ABI/testing/sysfs-class-net-statistics documentation is pointing to the wrong path for the interface. Documentation is pointing to /sys/class/<iface>, instead of /sys/class/net/<iface>. Fix it by adding the `net/` directory before the interface.

2024-02-12ALSA: doc: Use DEFINE_SIMPLE_DEV_PM_OPS()Takashi Iwai
Use the new DEFINE_SIMPLE_DEV_PM_OPS() instead of SIMPLE_DEV_PM_OPS() for the example code. This allows us to drop CONFIG_PM_SLEEP ifdefs. While we're at it, expand the driver definition instead of passing directly via .driver.pm field. This seems to be a more common pattern.

2024-02-12drm/nouveau: don't fini scheduler if not initializedDanilo Krummrich
nouveau_abi16_ioctl_channel_alloc() and nouveau_cli_init() simply call their corresponding *_fini() counterpart. This can lead to nouveau_sched_fini() being called without struct nouveau_sched ever being initialized in the first place. Instead of embedding struct nouveau_sched into struct nouveau_cli and struct nouveau_chan_abi16, allocate struct nouveau_sched separately, such that we can check for the corresponding pointer to be NULL in the particular *_fini() functions. It makes sense to allocate struct nouveau_sched separately anyway, since in a subsequent commit we can also avoid to allocate a struct nouveau_sched in nouveau_abi16_ioctl_channel_alloc() at all, if the VM_BIND uAPI has been disabled due to the legacy uAPI being used.

2024-02-12Merge branch 'mptcp-misc-fixes'David S. Miller
Matthieu Baerts says: ==================== mptcp: locking cleanup & misc. fixes Patches 1-4 are fixes for issues found by Paolo while working on adding TCP_NOTSENT_LOWAT support. The latter will need to track more states under the msk data lock. Since the locking msk locking schema is already quite complex, do a long awaited clean-up step by moving several confusing lockless initialization under the relevant locks. Note that it is unlikely a real race could happen even prior to such patches as the MPTCP-level state machine implicitly ensures proper serialization of the write accesses, even lacking explicit lock. But still, simplification is welcome and this will help for the maintenance. This can be backported up to v5.6. Patch 5 is a fix for the userspace PM, not to add new local address entries if the address is already in the list. This behaviour can be seen since v5.19. Patch 6 fixes an issue when Fastopen is used. The issue can happen since v6.2. A previous fix has already been applied, but not taking care of all cases according to syzbot.

2024-02-12mptcp: corner case locking for rx path fields initializationPaolo Abeni
Most MPTCP-level related fields are under the mptcp data lock protection, but are written one-off without such lock at MPC complete time, both for the client and the server Leverage the mptcp_propagate_state() infrastructure to move such initialization under the proper lock client-wise. The server side critical init steps are done by mptcp_subflow_fully_established(): ensure the caller properly held the relevant lock, and avoid acquiring the same lock in the nested scopes. There are no real potential races, as write access to such fields is implicitly serialized by the MPTCP state machine; the primary goal is consistency.

2024-02-12mptcp: fix rcv space initializationPaolo Abeni
mptcp_rcv_space_init() is supposed to happen under the msk socket lock, but active msk socket does that without such protection. Leverage the existing mptcp_propagate_state() helper to that extent. We need to ensure mptcp_rcv_space_init will happen before mptcp_rcv_space_adjust(), and the release_cb does not assure that: explicitly check for such condition. While at it, move the wnd_end initialization out of mptcp_rcv_space_init(), it never belonged there. Note that the race does not produce ill effect in practice, but change allows cleaning-up and defying better the locking model.

2024-02-12mptcp: drop the push_pending fieldPaolo Abeni
Such field is there to avoid acquiring the data lock in a few spots, but it adds complexity to the already non trivial locking schema. All the relevant call sites (mptcp-level re-injection, set socket options), are slow-path, drop such field in favor of 'cb_flags', adding the relevant locking. This patch could be seen as an improvement, instead of a fix. But it simplifies the next patch. The 'Fixes' tag has been added to help having this series backported to stable.

2024-02-12drm/i915/dsc: Fix the macro that calculates DSCC_/DSCA_ PPS reg addressManasi Navare
Commit bd077259d0a9 ("drm/i915/vdsc: Add function to read any PPS register") defines a new macro to calculate the DSC PPS register addresses with PPS number as an input. This macro correctly calculates the addresses till PPS 11 since the addresses increment by 4. So in that case the following macro works correctly to give correct register address: _MMIO(_DSCA_PPS_0 + (pps) * 4) However after PPS 11, the register address for PPS 12 increments by 12 because of RC Buffer memory allocation in between. Because of this discontinuity in the address space, the macro calculates wrong addresses for PPS 12 - 16 resulting into incorrect DSC PPS parameter value read/writes causing DSC corruption. This fixes it by correcting this macro to add the offset of 12 for PPS >=12. v3: Add correct paranthesis for pps argument (Jani Nikula) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/10172 Fixes: bd077259d0a9 ("drm/i915/vdsc: Add function to read any PPS register") Cc: Suraj Kandpal <suraj.kandpal@intel.com> Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Cc: Animesh Manna <animesh.manna@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Sean Paul <sean@poorly.run> Cc: Drew Davenport <ddavenport@chromium.org> Signed-off-by: Manasi Navare <navaremanasi@chromium.org> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240205204619.1991673-1-navaremanasi@chromium.org (cherry picked from commit 6074be620c31dc2ae11af96a1a5ea95580976fb5) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
