Subject: [PATCH] ACPI: battery: Evaluate battery methods exclusively
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On ThinkPad P1 Gen2 and P53, INT3403 _TMP switches the EC page selector
without taking the AML mutex the battery methods use, so _BIX and _BST
running at the same time can read the wrong page. Since commit d33e89d12295
("thermal: core: Suspend thermal zones later and resume them earlier")
this happens on most resumes.

Evaluate the battery methods with acpi_evaluate_object_exclusive().

Fixes: d33e89d12295 ("thermal: core: Suspend thermal zones later and resume them earlier")
