Subject: [PATCH v2 0/3] platform/x86 acer-wmi: Improve platform profile
 handling

This patch improves the platform profile handling for laptops using the
Acer Predator interface by making the following changes - 

1) Using WMI calls to fetch the current platform profile instead of
   directly accessing it from the EC.
2) Using an ACPI bitmap to dynamically set platform_profile_choices.
3) Simplifying the cycling of platform profiles by making use of
   platform_profile_cycle()

v1->v2:
[1]
   - Fixed enum member alignment and reordered them

[2]
   - Made use of test_bit to check bitmap values
   - Replaced magic numbers with proper variables

Link to v1: https://lore.kernel.org/platform-driver-x86/20241231140442.10076-1-hridesh699@gmail.com/
