media: dvb: as102-fe: Fix as10x_register_addr packing
[ Upstream commit 309422d280748c74f57f471559980268ac27732a ]
This structure is embedded in multiple other structures that are packed,
which conflicts with it being aligned.
drivers/media/usb/as102/as10x_cmd.h:379:30: warning: field reg_addr within 'struct as10x_dump_memory::(unnamed at drivers/media/usb/as102/as10x_cmd.h:373:2)' is less aligned than 'struct as10x_register_addr' and is usually due to 'struct as10x_dump_memory::(unnamed at drivers/media/usb/as102/as10x_cmd.h:373:2)' being packed, which can lead to unaligned accesses [-Wunaligned-access]
Mark it as being packed.
Marking the inner struct as 'packed' does not change the layout, since the
whole struct is already packed, it just silences the clang warning. See
also this llvm discussion:
