commit: 81d0a6ae7befb24c06f4aa4856af7f8d1f612171 From: Axel Lin <[email protected]> Date: Wed, 9 Jan 2013 19:34:57 +0800 Subject: regulator: max8998: Ensure enough delay time for max8998_set_voltage_buck_time_sel
Use DIV_ROUND_UP to prevent truncation by integer division issue. This ensures we return enough delay time.
