[PATCH 0/4] interconnect fixes for 5.5

[Georgi Djakov]

Hi Greg,

Here are some fixes for 5.5-rc. This includes fixing a linked list
corruption in some drivers and a Kconfig indentation fix. Two of
the patches are tagged for stable. Please apply to char-misc when
possible.

Thanks,
Georgi

[PATCH 2/4] interconnect: qcom: sdm845: Walk the list safely on node removal

[Georgi Djakov]

As we will remove items off the list using list_del(), we need to use the
safe version of list_for_each_entry().
