This is called from snd_ctl_elem_write() with user supplied data so we
need to add some bounds checking.

If the user passes an invalid value it leads to an info leak when we
print the error message or it could oops. This is called with user
supplied data from snd_ctl_elem_write().

After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

The MC13783 Chip Errata, Rev. 4 says, that depending on SPI clock
and main audio clock speed, the Audio Codec or Stereo DAC do sometimes
not start when programmed to do so. This is due to an internal clock
timing issue related to the loading of the SPI bits into the audio block.
On an i.MX27 based system, this issue lead to switched audio channels under
certain circumstances: RTC + Touch + Audio are used and loaded at startup.
The mentioned workaround of writing registers 40 and 41 two times is implemented
here.

The ssm2602 uses regmap for caching not soc-cache, so we need to use
regcache_sync() instead of snd_soc_cache_sync().

The core will call snd_soc_dapm_new_widgets() once all components of the card
have been initialized, so there is no need to do this manually in the driver.
Calling it earlier also might result in a partially instantiated system being
powered up which cause undesired side effects.

Let the core take care of instantiating the controls and DAPM widgets and
routes, this makes the code a bit shorter.

- DAPM is now mandatory for CODEC drivers in order to avoid the repeated
regressions in the special cases for non-DAPM CODECs and make it
easier to integrate with other components on boards. All existing
drivers have had some level of DAPM support added.
- A lot of cleanups in DAPM plus support for maintaining controls in a
specific state while a DAPM widget all contributed by Lars-Peter Clausen.
- Core helpers for bitbanged AC'97 reset from Markus Pargmann.
- New drivers and support for Analog Devices ADAU1702 and ADAU1401(a),
Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and WM8904 based
machines, Freescale S/PDIF and SSI AC'97, Renesas R-Car SoCs, Samsung
Exynos5420 SoCs, Texas Instruments PCM1681 and PCM1792A and Wolfson
Microelectronics WM8997.
- Support for building drivers that can support it cross-platform for
compile test.
