[PATCH] net: hns3: Add error handling for VLAN filter hardware configuration

by Wentao Liang

The hclge_rm_vport_vlan_table() calls hclge_set_vlan_filter_hw() but does not check the return value. This could lead to execution with potentially invalid data. A proper implementation can be found in hclge_add_vport_all_vlan_table(). Add error handling after calling hclge_set_vlan_filter_hw(). If hclge_set_vlan_filter_hw() fails, log an error message via dev_err() and return.

[PATCH net] phy: dp83869: fix interrupts issue when using with an optical fiber sfp. to correctly clear the interrupts both status registers must be read.

by chalianis1＠gmail.com

From: Anis Chali <chalianis1(a)gmail.com> from datasheet of dp83869hm 7.3.6 Interrupt The DP83869HM can be configured to generate an interrupt when changes of internal status occur. The interrupt allows a MAC to act upon the status in the PHY without polling the PHY registers. The interrupt source can be selected through the interrupt registers, MICR (12h) and FIBER_INT_EN (C18h). The interrupt status can be read from ISR (13h) and FIBER_INT_STTS (C19h) registers. Some interrupts are enabled by default and can be disabled through register access. Both the interrupt status registers must be read in order to clear pending interrupts. Until the pending interrupts are cleared, new interrupts may not be routed to the interrupt pin. Fixes: interrupts issue when using with an optical fiber sfp.

v2 [PATCH] ocfs2: fix panic in failed foilio allocation

by Mark Tinguely

In the page to order 0 folio conversion series, the commit 7e119cff9d0a, "ocfs2: convert w_pages to w_folios" and commit 9a5e08652dc4b, "ocfs2: use an array of folios instead of an array of pages", saves -ENOMEM in the folio array upon allocation failure and calls the folio array free code. The folio array free code expects either valid folio pointers or NULL. Finding the -ENOMEM will result in a panic. Fix by NULLing the error folio entry.

[PATCH] drm/i915/dp_mst: Work around Thunderbolt sink disconnect after SINK_COUNT_ESI read

by Imre Deak

Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT link may get disconnected inadvertently if the SINK_COUNT_ESI and the DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX transaction. Work around the issue by reading these registers in separate transactions. The issue affects MTL+ platforms and will be fixed in the DP-in adapter firmware, however releasing that firmware fix may take some time and is not guaranteed to be available for all systems. Based on this apply the workaround on affected platforms. See HSD #13013007775.
