[alsa-devel] [PATCH] ALSA: pcm: add const qualifier for read-only table for sampling rate

[Takashi Sakamoto]

There's a read-only table for each sampling rate, while it doesn't have
const qualifier and can be modified.

This commit add the qualifier. As a result, a symbol for the table
moves from .data section to .rodata.
