Subject: [PATCH][next] drm/i915/pmu: fix sizeof on attr, should be *attr
Date: Fri, 12 Jan 2018 17:36:03 +0000 [thread overview]
Message-ID: <20180112173603.28486-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
I believe the sizeof(attr) should be in fact sizeof(*attr), fortunately
the current code works because sizeof(struct attribute **) is the same
as sizeof(struct attribute *) for x86.
Detected by CoverityScan, CID#1463854 ("Sizeof not portable")
Fixes: 109ec558370f ("drm/i915/pmu: Only enumerate available counters in sysfs")
