From 23ab3cb314d945255e9734b509acf8cd21f6eee0 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 7 Nov 2025 13:04:56 +0200 Subject: [PATCH] drm/atomic: use drm_crtc_vblank_waitqueue() We have drm_crtc_vblank_waitqueue() to get the wait_queue_head_t pointer for a vblank. Use it instead of poking at dev->vblank[] directly. Due to the macro maze of wait_event_timeout() that uses the address-of operator on the argument, we have to pass it in with the indirection operator.
