[alsa-devel] [PATCH] ASoC: DaVinci: fix kernel panic due to uninitialized platform_data

[Manjunathappa, Prakash]

This patch fixes the Kernel panic issue on accessing davinci_vc in
cq93vc_probe function. struct davinci_vc is part of platform device's
private driver data(codec->dev->p->driver_data) and this is populated
by DaVinci Voice Codec MFD driver.
