These were getting the macros from an implicit module.h include via device.h, but we are planning to clean that up. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c This relatively recently added file uses EXPORT_SYMBOL and hence needs export.h included so that it is compatible with the module.h split up work.
