[PATCH] drm/panthor: Correct the order of arguments passed to gem_sync

From: Akash Goel

Date: Thu Mar 05 2026 - 06:13:46 EST


This commit corrects the order of arguments passed to panthor_gem_sync()
function, called when the SYNC_WAIT condition has to be evaluated for a
blocked GPU queue.

Fixes: cd2c9c3015e6 (drm/panthor: Add flag to map GEM object Write-Back Cacheable)
