The variable 'rv' is defined as unsigned type, so the following if
statement is invalid, we can modify the type of rv to int.
if (rv < 0) {
dev_err(cs35l56->dev, "irq: failed to get pm_runtime:
%d\n", rv);
goto err_unlock;
}
./sound/soc/codecs/cs35l56.c:333:5-7: WARNING: Unsigned expression compared with zero: rv < 0.
