Subject: compress: fix hpointer error when no sample rate
X-Git-Tag: v0.2.0~7
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=aad6a2a407624ae8c50a8eed105ba436f0414a38;p=tinycompress.git

compress: fix hpointer error when no sample rate

Fixes the oops() in compress_get_hpointer() to return
-ENODATA instead of errno if the sample rate is zero.
The value in errno here is not related to the reason
we are returning an error.
