This short series refactors the Ally suspend/resume functionality in the asus-wmi driver along with adding support for ROG Ally MCU version checking. The version checking is then used to toggle the use of older CSEE call hacks that were initially used to combat Ally suspend/wake issues arising from the MCU not clearing a particular flag on resume. ASUS have since corrected this especially for Linux in newer firmware versions. - hid-asus requests the MCU version and displays a warning if the version is older than the one that fixes the issue. - hid-asus awill also toggle the CSEE hack off, and mcu_powersave to on if the version is high enough. *Note: In review it was requested by Mario that I try strsep() for parsing the version. I did try this and a few variations but the result was much more code due to having to check more edge cases due to the input being raw bytes. In the end the cleaned up while loop proved more robust. - Changelog: + V2: https://lore.kernel.org/platform-driver-x86/20250226010129.32043-1-luke@xxxxxxxxxx/T/#t - Adjust warning message to explicitly mention suspend issues - Use switch/case block to set min_version - Set min_version to 0 by default and toggle hacks off + V3 - Remove noise (excess pr_info) - Use kstrtoint, not kstrtolong - Use __free(kfree) for allocated mem and drop goto + logging - Use print_hex_dump() to show failed data after pr_err in mcu_request_version() - Use pr_debug in set_ally_mcu_hack() and set_ally_mcu_powersave() plus correct the message.
