[PATCH] arm: mach-davinci: mark __maybe_unused struct

[PATCH] arm: mach-davinci: mark __maybe_unused struct

[Brian Norris]

If neither CONFIG_SND_DM365_AIC3X_CODEC nor CONFIG_SND_DM365_VOICE_CODEC
are defined, we may get warnings like:

    arch/arm/mach-davinci/board-dm365-evm.c:179:33: warning: 'dm365_evm_snd_data' defined but not used [-Wunused-variable]

To fix this, just mark the struct as __maybe_unused.

Thanks, will queue this for -rc cycle. For future, please note that
subject line of DaVinci patches need to be prefixed "ARM: davinci: ".
Also, the subject should highlight the answer to "Why?" rather than
"How?". So, while committing I changed the headline to:

ARM: davinci: dm365 evm: fix unused variable warning

Thanks,
Sekhar
