From be2d3e9d061552af6c50220ee7b7e76458a3080f Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 25 Apr 2024 12:39:20 +0200 Subject: [PATCH] drm/panthor: Kill the faulty_slots variable in panthor_sched_suspend() We can use upd_ctx.timedout_mask directly, and the faulty_slots update in the flush_caches_failed situation is never used.
