From: Daniel Vetter Date: Tue, 30 Sep 2014 08:56:43 +0000 (+0200) Subject: drm/i915: s/pm._irqs_disabled/pm.irqs_enabled/ X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2aeb7d3a4d425be7e9185e79dd745918f7f72552;p=linux-beck.git drm/i915: s/pm._irqs_disabled/pm.irqs_enabled/ Double negations just parse harder. Also this allows us to ditch some init code since clearing to 0 dtrt. Also ditch the assignment in intel_pm_setup, that's not redundant since we do the assignement now while setting up interrupts. While at it do engage in a bit of OCD and wrap up the few lines of setup/teardown code into little helper functions: intel_irq_fini for cleanup and intel_irq_init_hw for hw setup. v2: Use _install/_uninstall for the new wrapper function names as Paulo suggested.
