cpufreq: amd-pstate: Fix uninitialized variable in amd_pstate_cpu_boost_update()
Smatch complains that "ret" could be uninitialized: drivers/cpufreq/amd-pstate.c:734 amd_pstate_cpu_boost_update() error: uninitialized symbol 'ret'. This seems like it probably is a real issue. Initialize "ret" to zero to be safe.
