The structure is packed, which requires that all its fields need to be
also packed.
./include/uapi/linux/dvb/frontend.h:854:2: warning: field within 'struct dtv_stats' is less aligned than 'union dtv_stats::(anonymous at ./include/uapi/linux/dvb/frontend.h:854:2)' and is usually due to 'struct dtv_stats' being packed, which can lead to unaligned accesses [-Wunaligned-access]
Explicitly set the inner union as packed.
