arm64: topology: fix possible overflow in amu_fie_setup()
stable inclusion from stable-v5.10.150 commit 904f881b57360cf85de962d84d8614d94431f60e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=904f881b57360cf85de962d84d8614d94431f60e -------------------------------- cpufreq_get_hw_max_freq() returns max frequency in kHz as *unsigned int*, while freq_inv_set_max_ratio() gets passed this frequency in Hz as 'u64'. Multiplying max frequency by 1000 can potentially result in overflow -- multiplying by 1000ULL instead should avoid that...
