2024-06-13drm/bridge: sii902x: Fix mode_valid hookJayesh Choudhary
Currently, mode_valid is defined only in drm_connector_helper_funcs. When the bridge is attached with the 'DRM_BRIDGE_ATTACH_NO_CONNECTOR' flag, the connector is not initialized, and so is the mode_valid hook under connector helper funcs. It also returns MODE_OK for all modes without actually checking the modes. So move the mode_valid hook to drm_bridge_funcs with proper clock checks for maximum and minimum pixel clock supported by the bridge.

2024-06-13ice: avoid IRQ collision to fix init failure on ACPI S3 resumeEn-Wei Wu
A bug in https://bugzilla.kernel.org/show_bug.cgi?id=218906 describes that irdma would break and report hardware initialization failed after suspend/resume with Intel E810 NIC (tested on 6.9.0-rc5). The problem is caused due to the collision between the irq numbers requested in irdma and the irq numbers requested in other drivers after suspend/resume. The irq numbers used by irdma are derived from ice's ice_pf->msix_entries which stores mappings between MSI-X index and Linux interrupt number. It's supposed to be cleaned up when suspend and rebuilt in resume but it's not, causing irdma using the old irq numbers stored in the old ice_pf->msix_entries to request_irq() when resume. And eventually collide with other drivers. This patch fixes this problem. On suspend, we call ice_deinit_rdma() to clean up the ice_pf->msix_entries (and free the MSI-X vectors used by irdma if we've dynamically allocated them). On resume, we call ice_init_rdma() to rebuild the ice_pf->msix_entries (and allocate the MSI-X vectors if we would like to dynamically allocate them).

2024-06-13bnxt_en: Adjust logging of firmware messages in case of released token in ↵Aleksandr Mishin
__hwrm_send() In case of token is released due to token->state == BNXT_HWRM_DEFERRED, released token (set to NULL) is used in log messages. This issue is expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But this error code is returned by recent firmware. So some firmware may not return it. This may lead to NULL pointer dereference. Adjust this issue by adding token pointer check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2024-06-13bnxt_en: Cap the size of HWRM_PORT_PHY_QCFG forwarded responseMichael Chan
Firmware interface 1.10.2.118 has increased the size of HWRM_PORT_PHY_QCFG response beyond the maximum size that can be forwarded. When the VF's link state is not the default auto state, the PF will need to forward the response back to the VF to indicate the forced state. This regression may cause the VF to fail to initialize. Fix it by capping the HWRM_PORT_PHY_QCFG response to the maximum 96 bytes. The SPEEDS2_SUPPORTED flag needs to be cleared because the new speeds2 fields are beyond the legacy structure. Also modify bnxt_hwrm_fwd_resp() to print a warning if the message size exceeds 96 bytes to make this failure more obvious.

2024-06-13.editorconfig: remove trim_trailing_whitespace optionGreg Kroah-Hartman
Some editors (like the vim variants), when seeing "trim_whitespace" decide to do just that for all of the whitespace in the file you are saving, even if it is not on a line that you have modified. This plays havoc with diffs and is NOT something that should be intended. As the "only trim whitespace on modified lines" is not part of the editorconfig standard yet, just delete these lines from the .editorconfig file so that we don't end up with diffs that are automatically rejected by maintainers for containing things they shouldn't.

2024-06-13drm/i915/dp_mst: Fix DSC input BPP computationImre Deak
The branch or sink device decompressing a stream may have a limitation on the input/uncompressed BPP, which is lower than the base line BPP (determined by the sink's EDID). In some cases a stream with an input BPP higher than this limit will be converted automatically by the device decompressing the stream, by truncating the BPP, however in some cases - seen at least in Dell dock's DP->HDMI converters - the decompression will fail. Fix the above by limiting the input BPP correctly. This is done already correctly for SST outputs.

2024-06-13ionic: fix use after netif_napi_del()Taehee Yoo
When queues are started, netif_napi_add() and napi_enable() are called. If there are 4 queues and only 3 queues are used for the current configuration, only 3 queues' napi should be registered and enabled. The ionic_qcq_enable() checks whether the .poll pointer is not NULL for enabling only the using queue' napi. Unused queues' napi will not be registered by netif_napi_add(), so the .poll pointer indicates NULL. But it couldn't distinguish whether the napi was unregistered or not because netif_napi_del() doesn't reset the .poll pointer to NULL. So, ionic_qcq_enable() calls napi_enable() for the queue, which was unregistered by netif_napi_del().

2024-06-13drm/xe/pf: Assert LMEM provisioning is done only on DGFXMichal Wajdeczko
The Local Memory (aka VRAM) is only available on DGFX platforms. We shouldn't attempt to provision VFs with LMEM or attempt to update the LMTT on non-DGFX platforms. Add missing asserts that would enforce that and fix release code that could crash on iGFX due to uninitialized LMTT.

After starting to install the EC address space handler at the ACPI namespace root, if there is an "orphan" _REG method in the EC device's scope, it will not be evaluated any more. This breaks EC operation regions on some systems, like Asus gu605. To address this, use a wrapper around an existing ACPICA function to look for an "orphan" _REG method in the EC device scope and evaluate it if present.

2024-06-12net/ipv6: Fix the RT cache flush via sysctl using a previous delayPetr Pavlu
The net.ipv6.route.flush system parameter takes a value which specifies a delay used during the flush operation for aging exception routes. The written value is however not used in the currently requested flush and instead utilized only in the next one. A problem is that ipv6_sysctl_rtcache_flush() first reads the old value of net->ipv6.sysctl.flush_delay into a local delay variable and then calls proc_dointvec() which actually updates the sysctl based on the provided input. Fix the problem by switching the order of the two operations. Fixes: 4990509f19e8 ("[NETNS][IPV6]: Make sysctls route per namespace.")
