[PATCH 2/2] drm/tegra: Zero-initialize iosys_map

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Mikko Perttunen <mperttunen@xxxxxxxxxx>

UBSAN reports an invalid load for bool, as the iosys_map is read
later without being initialized. Zero-initialize it to avoid this.
