Subject: ASoC: sigmadsp: Fix missleading return value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=61c4a1ac4d900e743af0b363fe520405939eab47;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ASoC: sigmadsp: Fix missleading return value

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.
