Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops. The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.

HDSPM driver contains a code issuing zero-division potentially in
system sample rate ctl code. This patch fixes it by not processing
a zero or invalid rate value as a divisor, as well as excluding the
invalid value to be passed via the given ctl element.

Use the new snd_pcm_hw_constraint_single() helper function instead of
calling snd_pcm_hw_constraint_minmax() with the same value for min and max
to install a constraint that limits the possible configuration values to a
single value. Using snd_pcm_hw_constraint_single() makes the indented
result clearer.

RME RayDAT and AIO use a fixed buffer size of 16384 samples. With period
sizes of 32-4096, this translates to 4-512 periods.
The older RME cards have a variable buffer size but require exactly two
periods.
This patch enforces nperiods=2 on those cards.

Use enum hdspm_ltc_format's fps_30 (corresponds to 4) instead of 30,
Other case branches return 1, 2 or 3 respectively, so 30 obviously is

AIO cards offer at least four individual settings options with three
states each. Those settings are represented as two bits in the settings
register with the following meaning:
0*some_base_bit --> Option value 0
1*some_base_bit --> Option value 1
2*some_base_bit --> Option value 2
3*some_base_bit --> mask to select the two involved bits
This patch adds a generic ALSA control macro for such a value-to-bit
pattern mapping. It will be used in a later commit to expose four new
controls.
