Hello Andy, when I feed attached file to checkpatch, several warnings are given, but this one: WARNING: externs should be avoided in .c files #3555: FILE: staging/brcm80211/brcmsmac/main.c:3555: + END_FOREACH_BSS does not seem to make sense. When I place a comment behind the END_FOREACH_BSS line, the checkpatch warning disappears. Let me know if you need additional info to work on this. Thanks, Roland Vossen Broadcom
