[PATCH 2/3] media: dvb: Fix dtvs_stats packing.

From: Ricardo Ribalda
Date: Wed Apr 10 2024 - 08:25:05 EST


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.
