Revision e9ba4032a2568ef5b360de95eb6e09195a1b2efd authored by Maarten Lankhorst on 17 July 2017, 11:13:55 UTC, committed by Daniel Vetter on 27 July 2017, 20:07:29 UTC
ddb_allocation && ddb_allocation / blocks_per_line >= 1 is the same as ddb_allocation >= blocks_per_line, so use the latter to simplify this. This fixes the following compiler warning: drivers/gpu/drm/i915/intel_pm.c:4467]: (warning) Comparison of a boolean expression with an integer other than 0 or 1.
