[ Upstream commit e61f9ea271933d987ab895c689fa37744f6fc27f ]
In case of error, the function i2c_new_dummy_device() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().
Fixes: e6089feca460 ("media: m88ds3103: Add support for ds3103b demod")
