X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Dhinakaran Pandiyan MIME-Version: 1.0 Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" X-Virus-Scanned: ClamAV using ClamSMTP gen8_de_irq_postinstall() wasn't masking the IRQ bit before passing the debug flag to psr_irq_control(). This check was missed when new debug bits were defined in 'commit c44301fce614 ("drm/i915: Allow control of PSR at runtime through debugfs, v6")'. Instead of ANDing the irq bit in all the callers, move it to the callee.
