Subject: [PATCH v2 0/2] sched/deadline: fixes and improvements

Hello,

This patch series addresses specific issues and improvements within
the scheduler's deadline (DL) class. The patches aim to fix warnings,
remove redundant checks, and consolidate timer cancellation logic for
better consistency and code quality.

Patch 1: Fix warning in migrate_enable for boosted tasks

Fix a warning caused by unnecessary calls to setup_new_dl_entity for
boosted tasks during CPU migate_enable calls.

Patch 2: sched/deadline: Consolidate Timer Cancellation

Consolidate timer cancellation logic into dedicated functions,
ensuring consistent behavior and reducing code duplication.

Changelog
---------

v2:
* Drop patch to remove the redundant WARN_ON call.
* Change the "Fixes" tag in the patch 1.
* Change function names in the patch 2.
