Merge patch series "clk: Return value calculated by ERR_PTR"

Andrew Goodbody <andrew.goodbody@linaro.org> says:

Smatch reported an error where a value calculated by ERR_PTR was not
used. Fixing this to return the generated value led to a test failure
which meant updating the sandbox clock code so that it would still cause
the tests to pass with the above correction.
Debugging this problem led to a SIGSEGV which is addressed in 1/3.
Possible memory leaks noticed are addressed in 3/3.
