Move enabling and disabling HDMI_EN optional regulator to probe() function to keep track on the regulator status. This fixes following warning if probe() fails (for example when I2C DDC adapter cannot be yet gathered due to the missing driver). This fixes following warning observed on Arndale5250 board with multi_v7_defconfig: [drm] Failed to get ddc i2c adapter by node ------------[ cut here ]------------ WARNING: CPU: 0 PID: 214 at drivers/regulator/core.c:2051 _regulator_put+0x16c/0x184 Modules linked in: ...
