From b8d19bf463893a07bab9120bd628798515f3e6e0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 140/323] net: sundance: Use tasklet_disable_in_atomic().
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
tasklet_disable() is used in the timer callback. This might be distangled,
but without access to the hardware that's a bit risky.
Replace it with tasklet_disable_in_atomic() so tasklet_disable() can be
changed to a sleep wait once all remaining atomic users are converted.
