[PATCH v2 21/25] ASoC: renesas: msiof: Remove redundant period constraint

From: phucduc . bui

Date: Wed Oct 14 2026 - 21:50:54 EST


From: bui duc phuc <phucduc.bui@xxxxxxxxx>

snd_pcm_hw_constraint_integer() is already called by
snd_dmaengine_pcm_open(). Calling it again in msiof_open() is
unnecessary, as the constraint is already applied and the second
call returns 0.

Remove the redundant constraint call.

Signed-off-by: bui duc phuc <phucduc.bui@xxxxxxxxx>

Changes in v2:
- Remove redundant integer constraints already applied by
snd_dmaengine_pcm_open().
