[PATCH -next] gpio: Fix return value check in owl_gpio_probe()

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

 



In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
