| Subject: backlight: lm3630a: Initialize backlight_properties on init |
| |
| From: Luca Weiss <luca@z3ntu.xyz> |
| |
| [ Upstream commit ad9aeb0e3aa90ebdad5fabf9c21783740eb95907 ] |
| |
| The backlight_properties struct should be initialized to zero before |
| using, otherwise there will be some random values in the struct. |
