[ Upstream commit 014eccc9da7bfc76a3107fceea37dd60f1d63630 ]
The HVS can change AXI request mode based on how full the COB FIFOs are. Until now the vc4 driver has been relying on the firmware to have set these to sensible values.
With HVS channel 2 now being used for live video, change the panic mode for all channels to be explicitly set by the driver, and the same for all channels.

Add quirk orientation for AYA NEO 2. The name appears without spaces in DMI strings. That made it difficult to reuse the 2021 match. Also the display is larger in resolution.
Tested by the JELOS team that has been patching their own kernel for a while now and confirmed by users in the AYA NEO and ChimeraOS discord servers.

sock_init_data() attaches the allocated sk pointer to the provided sock object. If inet6_create() fails later, the sk object is released, but the sock object retains the dangling sk pointer, which may cause use-after-free later.
Clear the sock sk pointer on error.

Original commit message: "Why: Setting IH_RB_WPTR register to 0 will not clear the RB_OVERFLOW bit if RB_ENABLE is not set.
How to fix: Set WPTR_OVERFLOW_CLEAR bit after RB_ENABLE bit is set. The RB_ENABLE bit is required to be set, together with WPTR_OVERFLOW_ENABLE bit so that setting WPTR_OVERFLOW_CLEAR bit would clear the RB_OVERFLOW."

radix_lock() shouldn't be held while holding dma_hash_entry[idx].lock otherwise, there's a possible deadlock scenario when dma debug API is called holding rq_lock():
CPU0 CPU1 CPU2 dma_free_attrs() check_unmap() add_dma_entry() __schedule() //out (A) rq_lock() get_hash_bucket() (A) dma_entry_hash check_sync() (A) radix_lock() (W) dma_entry_hash dma_entry_free() (W) radix_lock() // CPU2's one (W) rq_lock()
CPU1 situation can happen when it extending radix tree and it tries to wake up kswapd via wake_all_kswapd().
CPU2 situation can happen while perf_event_task_sched_out() (i.e. dma sync operation is called while deleting perf_event using etm and etr tmc which are Arm Coresight hwtracing driver backends).
To remove this possible situation, call dma_entry_free() after put_hash_bucket() in check_unmap().

[ Upstream commit 857282b819cbaa0675aaab1e7542e2c0579f52d7 ]
This patch fixes a NULL pointer dereference bug in brcmfmac that occurs when a high 'sd_sgentry_align' value applies (e.g. 512) and a lot of queued SKBs are sent from the pkt queue.
The problem is the number of entries in the pre-allocated sgtable, it is nents = max(rxglom_size, txglom_size) + max(rxglom_size, txglom_size) >> 4 + 1. Given the default [rt]xglom_size=32 it's actually 35 which is too small. Worst case, the pkt queue can end up with 64 SKBs. This occurs when a new SKB is added for each original SKB if tailroom isn't enough to hold tail_pad. At least one sg entry is needed for each SKB. So, eventually the "skb_queue_walk loop" in brcmf_sdiod_sglist_rw may run out of sg entries. This makes sg_next return NULL and this causes the oops.
The patch sets nents to max(rxglom_size, txglom_size) * 2 to be able handle the worst-case. Btw. this requires only 64-35=29 * 16 (or 20 if CONFIG_NEED_SG_DMA_LENGTH) = 464 additional bytes of memory.

[ Upstream commit 82ff5abc2edcfba0c0f1a1be807795e2876f46e9 ]
The ordering in hdmi_codec_get_ch_alloc_table_idx() results in wrong channel allocation for a number of cases, e.g. when ELD reports FL|FR|LFE|FC|RL|RR or FL|FR|LFE|FC|RL|RR|RC|RLC|RRC:
ca_id 0x01 with speaker mask FL|FR|LFE is selected instead of ca_id 0x03 with speaker mask FL|FR|LFE|FC for 4 channels
and
ca_id 0x04 with speaker mask FL|FR|RC gets selected instead of ca_id 0x0b with speaker mask FL|FR|LFE|FC|RL|RR for 6 channels
Fix this by reordering the channel allocation list with most specific speaker masks at the top.

Since '1 << rocker_port->pport' may be undefined for port >= 32, cast the left operand to 'unsigned long long' like it's done in 'rocker_port_set_enable()' above. Compile tested only.

Commit 51183d233b5a ("net/neighbor: Update neigh_dump_info for strict data checking") added strict checking. The err variable is not cleared, so if we find no table to dump we will return the validation error even if user did not want strict checking.
I think the only way to hit this is to send an buggy request, and ask for a table which doesn't exist, so there's no point treating this as a real fix. I only noticed it because a syzbot repro depended on it to trigger another bug.

The ndev->npinfo pointer in __netpoll_setup() is RCU-protected but is being accessed directly for a NULL check. While no RCU read lock is held in this context, we should still use proper RCU primitives for consistency and correctness.
Replace the direct NULL check with rcu_access_pointer(), which is the appropriate primitive when only checking for NULL without dereferencing the pointer. This function provides the necessary ordering guarantees without requiring RCU read-side protection.
