This is a note to let you know that I've just added the patch titled platform/x86/intel: punit_ipc: Drop wrong use of ACPI_PTR() to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: platform-x86-intel-punit_ipc-drop-wrong-use-of-acpi_.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d5780e3e6bbe86a1054c26258719e3e91e40ca90 Author: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Date: Fri Aug 27 17:53:10 2021 +0300 platform/x86/intel: punit_ipc: Drop wrong use of ACPI_PTR() [ Upstream commit 349bff48ae0f5f8aa2075d0bdc2091a30bd634f6 ] ACPI_PTR() is more harmful than helpful. For example, in this case if CONFIG_ACPI=n, the ID table left unused which is not what we want. Instead of adding ifdeffery here and there, drop ACPI_PTR() and unused acpi.h.
