Fix a memory leak in the NVIDIA Tegra ASoC machine driver where
allocated DAPM widget lists were never freed. The function
dpcm_runtime_set_dai_fmt() calls snd_soc_dapm_dai_get_connected_widgets()
which allocates memory for a widget list, but was returning without
calling snd_soc_dapm_dai_free_widgets() to free this memory.
The leak was detected by kmemleak:
unreferenced object 0xffff00008fc7e300 (size 192):
comm "alsactl", pid 812, jiffies 4294900395
backtrace:
kmemleak_alloc+0xc0/0xe8
__kmalloc+0x2e0/0x4c8
snd_soc_dapm_dai_get_connected_widgets+0x108/0x2a0
Fix this by using snd_soc_dapm_dai_free_widgets() on
success or failure to ensure the widget list is always freed
before returning.
