2021-12-29ASoC: rt5682: Register wclk with its parent_hws instead of parent_dataDerek Fang
The mclk might not be registered as a fixed clk name "mclk" on some platforms. In those platforms, if the mclk needed to be controlled by codec driver and acquired by a fixed name, it would be a problem. This patch to fix the issue that wclk becomes an orphan due to the fixed mclk's name.

2021-12-29ASoC: mediatek: mt8195: update control for RT5682 seriesTrevor Wu
Playback pop is observed and the root cause is the reference clock provided by MT8195 is diabled before RT5682 finishes the control flow. To ensure the reference clock supplied to RT5682 is disabled after RT5682 finishes all register controls. We replace BCLK with MCLK for RT5682 reference clock, and makes use of set_bias_level_post to handle MCLK which guarantees MCLK is off after all RT5682 register access.

2021-12-28net/mlx5e: Fix wrong features assignment in case of errorGal Pressman
In case of an error in mlx5e_set_features(), 'netdev->features' must be updated with the correct state of the device to indicate which features were updated successfully. To do that we maintain a copy of 'netdev->features' and update it after successful feature changes, so we can assign it to back to 'netdev->features' if needed. However, since not all netdev features are handled by the driver (e.g. GRO/TSO/etc), some features may not be updated correctly in case of an error updating another feature. For example, while requesting to disable TSO (feature which is not handled by the driver) and enable HW-GRO, if an error occurs during HW-GRO enable, 'oper_features' will be assigned with 'netdev->features' and HW-GRO turned off. TSO will remain enabled in such case, which is a bug. To solve that, instead of using 'netdev->features' as the baseline of 'oper_features' and changing it on set feature success, use 'features' instead and update it in case of errors.

2021-12-28libbpf: Use 100-character limit to make bpf_tracing.h easier to readAndrii Nakryiko
Improve bpf_tracing.h's macro definition readability by keeping them single-line and better aligned. This makes it easier to follow all those variadic patterns.

2021-12-28libbpf: Normalize PT_REGS_xxx() macro definitionsAndrii Nakryiko
Refactor PT_REGS macros definitions in bpf_tracing.h to avoid excessive duplication. We currently have classic PT_REGS_xxx() and CO-RE-enabled PT_REGS_xxx_CORE(). We are about to add also _SYSCALL variants, which would require excessive copying of all the per-architecture definitions. Instead, separate architecture-specific field/register names from the final macro that utilize them. That way for upcoming _SYSCALL variants we'll be able to just define x86_64 exception and otherwise have one common set of _SYSCALL macro definitions common for all architectures.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== 10GbE Intel Wired LAN Driver Updates 2021-12-28 Alexander Lobakin says: napi_build_skb() I introduced earlier this year ([0]) aims to decrease MM pressure and the overhead from in-place kmem_cache_alloc() on each Rx entry processing by decaching skbuff_heads from NAPI per-cpu cache filled prior to that by napi_consume_skb() (so it is sort of a direct shortcut for free -> mm -> alloc cycle). Currently, no in-tree drivers use it.
