[alsa-devel] [PATCH] ASoC: sigmadsp: Fix missleading return value

[pascal.huerst at gmail.com]

From: Pascal Huerst <pascal.huerst at gmail.com>

Forwarding the return value of i2c_master_send, leads to errors
later on, since i2c_master_send returns the number of bytes
transmittet. Check for ret < 0 instead and return 0 otherwise.
