Uwe Kleine-König 292c0f3b4a pwm: sifive: Call pwm_sifive_update_clock() while mutex is held ... [ Upstream commit 45558b3abb ] As was documented in commit 0f02f491b7 ("pwm: sifive: Reduce time the controller lock is held") a caller of pwm_sifive_update_clock() must hold the mutex. So fix pwm_sifive_clock_notifier() to grab the lock. While this necessity was only documented later, the race exists since the driver was introduced.
