Subject: Driver core: Fix cleanup in device_create_vargs().
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=286661b3777897220ecfcd774bccc68a34667f39;p=openwrt%2Fstaging%2Fblogic.git

Driver core: Fix cleanup in device_create_vargs().

If device_register() in device_create_vargs() fails, the device
must be cleaned up with put_device() (which is also fine on NULL)
instead of kfree().
