[PATCH] regmap: kunit: Fix an NULL vs IS_ERR() check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The kunit_device_register() function returns error pointers, not NULL.
Passing an error pointer to get_device() will lead to an Oops.  Also
get_device() returns the same device you passed to it.  Fix it!  ;)
