All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0xe79f2a): Section mismatch in reference from the function ieee80211_find_sta() to the variable .init.text:.L0
The function ieee80211_find_sta() references
the variable __init .L0 .
This is often because ieee80211_find_sta lacks a __init
annotation or the annotation of .L0 is wrong.

Note: the below error/warnings can be found in parent commit:
