Takashi Iwai 57a4451d26 ALSA: Use strlcpy() instead of strncpy()
We tend to make stupid mistakes with strncpy().  Let's take a safer
one, strlcpy().

Takashi Iwai 6913a9dbf1 ASoC: Updates for v3.13
- Further work on the dmaengine helpers, including support for
    configuring the parameters for DMA by reading the capabilities of the
    DMA controller which removes some guesswork and magic numbers fromm
    drivers.
  - A refresh of the documentation.
  - Conversions of many drivers to direct regmap API usage in order to
    allow the ASoC level register I/O code to be removed, this will
    hopefully be completed by v3.14.
  - Support for using async register I/O in DAPM, reducing the time taken
    to implement power transitions on systems that support it.
