Subject: [PATCH v2 00/14] ASoC: Constify local snd_sof_dsp_ops

Hi,

Changes in v2
=============
- Only rebase on for-next of broonie/sound.git
- Add tags.
- Link to v1: https://lore.kernel.org/r/20240414-n-const-ops-var-v1-0-8f53ee5d981c@kernel.org

Description
===========
The core code does not modify the 'struct snd_sof_dsp_ops' passed via
pointer in various places, so this can be made pointer to const in few
places.  This in turn allows few drivers to have the local (usually
static) 'struct snd_sof_dsp_ops' as const which increased code safety,
as it is now part of rodata.

Not all drivers can be made safer that way. Intel and AMD rely on
customizing that 'struct snd_sof_dsp_ops' before passing to SOF, so they
won't benefit.  They don't lose anything., either.

All further patches depend on the first four patches.

Best regards,
Krzysztof
