commit 6744085079e785dae5f7a2239456135407c58b25 upstream. The of_platform_populate() call at the end of the function has a possible failure path, causing a resource leak.

tegra_emc_find_node_by_ram_code() [ Upstream commit b9784e5cde1f9fb83661a70e580e381ae1264d12 ] As of_find_node_by_name() release the reference of the argument device node, tegra_emc_find_node_by_ram_code() releases some device nodes while still in use, resulting in possible UAFs. According to the bindings and the in-tree DTS files, the "emc-tables" node is always device's child node with the property "nvidia,use-ram-code", and the "lpddr2" node is a child of the "emc-tables" node. Thus utilize the for_each_child_of_node() macro and of_get_child_by_name() instead of of_find_node_by_name() to simplify the code. This bug was found by an experimental verification tool that I am developing.

2024-08-25memory: ti-aemif: Revert "memory: ti-aemif: don't needlessly iterate over ↵Bartosz Golaszewski1-3/+5
child nodes" This reverts commit 23a641d5c2bce4c723fff9118a5d865ee6b9d05a. The first-level children of the aemif node are not the device nodes (ones containing the 'compatible' property) but the chip-select nodes which instead have their own children. of_platform_populate() will skip such nodes so we must indeed iterate over the direct children of the aemif node. The problem here is that we never call of_platform_depopulate() as it takes the root device as argument. We only have an unpopulated chip-select nodes so we will leak these devices if any of the calls to of_platform_populate() fails. I don't have a batter idea right now but my patch was not correct so we need to revert it. While at it: at least use the scoped variant of the OF node iterator. Down the line, we should find a better solution to fix this potential resource leak in error path.

Fix incorrect comment on periodic_compensation_handler() as the call update_clock_tree_delay() with DVFS_UPDATE is responsible for dividing the samples accumulated up to that point and comparing the computed values with the currently programmed ones. While at it fix the indentation of a nearby comment.
