drm_hwcomposer: Fix another build warning in HwcDisplay::SetPowerMode()
Building with AOSP I see:
external/drm_hwcomposer/hwc2_device/HwcDisplay.cpp:768:50: warning: format specifies type 'int' but the argument has type 'HWC2::PowerMode' [-Wformat]
768 | ALOGE("Incorrect power mode value (%d)\n", mode);
| ~~ ^~~~
| static_cast<int>(
So this patch tweaks the message to use integer mode_in argument
to the function.
