Subject: [PATCH v3] ptp: fix an IS_ERR() vs NULL check
Date: Fri, 7 Dec 2018 09:00:46 +0300 [thread overview]
Message-ID: <20181207060046.GA3943@unbuntlaptop> (raw)
In-Reply-To: <20181206135719.GA18607@kroah.com>
We recently modified pps_register_source() to return error pointers
instead of NULL but it seems like there was a merge issue and part of
the commit was lost. Anyway, the ptp_clock_register() function needs to
be updated to check for IS_ERR() as well.
Fixes: 3b1ad360acad ("pps: using ERR_PTR instead of NULL while pps_register_source fails")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>

v2: Use the correct Fixes tag.
