Subject: [PATCH] PCI: dwc: kirin: Use PTR_ERR_OR_ZERO
Date: Mon, 16 Nov 2020 16:44:03 +0000	[thread overview]
Message-ID: <20201116164403.25289-1-sudipm.mukherjee@gmail.com> (raw)

Coccinelle suggested using PTR_ERR_OR_ZERO() and looking at the code,
we can use PTR_ERR_OR_ZERO() instead of checking IS_ERR() and then
doing 'return 0'.
