Subject: Clang warning in drivers/gpu/drm/i915/i915_debugfs.c
Date: Tue, 8 Jan 2019 12:13:14 -0700	[thread overview]
Message-ID: <20190108191314.GA25250@flashbox> (raw)

Hi all,

Commit e845f099f1c6 ("drm/i915/dsc: Add Per connector debugfs node for
DSC support/enable") causes a Clang warning:

drivers/gpu/drm/i915/i915_debugfs.c:4961:17: warning: address of array 'intel_dp->dsc_dpcd' will always evaluate to 'true' [-Wpointer-bool-conversion]
                if (intel_dp->dsc_dpcd)
                ~~  ~~~~~~~~~~^~~~~~~~
1 warning generated.

Did you mean to dereference it or should that print statement just
always show? I normally would send a patch myself but since I'm not
familiar with this code, I'd rather not shoot in the dark :) especially
since it's for a trivial logging statement.

Thanks,
Nathan
