Subject: [PATCH] misc: hisi_hikey_usb: use PTR_ERR_OR_ZERO
Date: Mon, 26 Oct 2020 18:00:26 +0000 [thread overview]
Message-ID: <20201026180026.3350-1-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'.
