+Subject: [PATCH 074/114] TAS5713: return error if initialisation fails
+
+Existing TAS5713 driver logs errors during initialisation, but does not return
+an error code. Therefore even if initialisation fails, the driver will still be
+loaded, but won't work. This patch fixes this. I2C communication error will now
+reported correctly by a non-zero return code.
