of: unittest: remove unneeded local return value variables
A common pattern in many unittest functions is to save the return value of a function in a local variable, then test the value of the local variable, without using that return value for any further purpose. Remove the local return value variable for these cases. A second common pattern is: ret = some_test_function(many, parameters, ...); if (unittest(ret == 0, "error message format", ...)) return; This pattern is more clear when the local variable 'ret' is used, due to the long lines caused by the parameters to the test function and the long format and data parameters of unittest(). The local variable is retained in these cases. Signed-off-by: Frank Rowand <[email protected]> Signed-off-by: Rob Herring <[email protected]>
