X-Git-Tag: v5.15~10070^2~73
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b08e19defc10befc50af09771ff0b086f2a72138;p=platform%2Fkernel%2Flinux-starfive.git

s390/char: fix cdev_add usage

Function cdev_add does set cdev->dev, so there is no point in setting
it prior to calling this function.
