Subject: drm/i915/bios: add missing __packed to structs used for reading vbt
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4dc49272bdfc11cdefb41175771ee811e363dfc7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/bios: add missing __packed to structs used for reading vbt

This does not seem to make a difference for the structs in question, but
document the intent.

v2: also pack union child_device_config (Daniel)
