Denis RastyoginandMark Brown f9e437cddf ASoC: rsnd: Fix potential out-of-bounds access of component_dais[]
component_dais[RSND_MAX_COMPONENT] is initially zero-initialized
and later populated in rsnd_dai_of_node(). However, the existing boundary check:
  if (i >= RSND_MAX_COMPONENT)

does not guarantee that the last valid element remains zero. As a result,
the loop can rely on component_dais[RSND_MAX_COMPONENT] being zero,
which may lead to an out-of-bounds access.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
