[PATCH 5.12 362/677] media: m88ds3103: fix return value check in m88ds3103_probe()
From: Greg Kroah-Hartman
Date: Wed May 12 2021 - 14:46:35 EST
From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>
[ 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")
