Subject: [PATCH] Driver core: send hotplug event before adding class interfaces
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dbe9035d4f690c44b55d3d0f1bc193e2c3fc57fa;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] Driver core: send hotplug event before adding class interfaces

Move call to kobject_hotplug() above code that adds interfaces
to a class device, otherwise children's hotplug events may reach
userspace first.
