Subject: [PATCH] driver core: Fix up the device_attach() error handling in bus_add_device()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d377e85b537a5e166272f937da6ba84350676b6e;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] driver core: Fix up the device_attach() error handling in bus_add_device()

Don't error out if something "bad" happens when trying to bind a driver to a
device.  We want the sysfs attributes to be present for later when we try to
tear down the device.
