From: Ville Syrjälä Date: Fri, 17 Jan 2014 09:35:15 +0000 (+0200) Subject: drm/i915: Make irq_received bool X-Git-Tag: next-20140306~57^2~4^2~99 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=501e01d7cd08d1fc5d876ca6e8162e19e012ac76;p=karo-tx-linux.git drm/i915: Make irq_received bool irq_received is used as a boolean in i965_irq_handler(), so make it bool. This also makes i965_irq_handler() closer to i915_irq_handler().
