The\nI2C access resumes this I2C bus controller via .runtime_resume callback,\nwhich calls clk_prepare_enable(), which attempts to grab the prepare_lock\nmutex again and deadlocks.\n\nSince the clock are already prepared since probe() and unprepared in\nremove(), use simple clk_enable()/clk_disable() calls to enable and\ndisable the clock on runtime suspend and resume, to avoid hitting the\nprepare_lock mutex."
