From 82d8eb40bab10082050be945c8e7096df8e9f989 Mon Sep 17 00:00:00 2001 From: Rhyland Klein Date: Thu, 12 May 2016 13:45:04 -0400 Subject: mfd: max77620: Fix FPS switch statements When configuring FPS during probe, assuming a DT node is present for FPS, the code can run into a problem with the switch statements in max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely, in the case of chip->chip_id == MAX77620, it will set fps_[mix|max]_period but then fall through to the default switch case and return -EINVAL. Returning this from max77620_config_fps() will cause probe to fail.
