Subject: i2c-dev: Return correct error code on class_create() failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e74783ec3cb981211689bd2cfd3248f8dc48ec01;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

i2c-dev: Return correct error code on class_create() failure

We need to convert the error pointer from class_create(), else we'll return the
successful return code from register_chrdev() on failure.
