Subject: i40iw: Replace list_for_each_entry macro with safe version
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a05e15135b67d71f30f70ab45dede4706f988439;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

i40iw: Replace list_for_each_entry macro with safe version

Use list_for_each_entry_safe macro for the IPv6 addr list
as IPv6 addresses can be deleted while going through the
list.
