similar to: [PATCH] nouveau/gsp: drop some acpi related debug

This is a collection of nouveau debug prints, memory leak, a very annoying race condition causing system hangs with prime scenarios, and a fix from Lyude to get the panel on my laptop working. I'd like to get these into 6.7, Dave.

From: Dave Airlie <airlied at redhat.com> These WARN_ONs seem to trigger a lot, and we don't seem to have a plan to fix them, so just drop them, as they are most likely harmless.

This patch certainly needs some more work, but I'd like to get some comments. Not sure if it is really related to the gmux or if it is a different Optimus _DSM version. I tested it on my laptop (MCP79/7A + G96) and the G96 successfully goes to sleep, however it is still marked as PWR in vga_switcheroo, despite `vga_switcheroo_set_dynamic_switch(pdev, VGA_SWITCHEROO_OFF)` being called. ---

This is especially true when variables or functions are just called dsm without precising the v1.

acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use uuid_le type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. The conversion fixes a potential bug in int340x_thermal as well since we have to use memcmp() on binary data. Cc: Rafael J. Wysocki <rjw

Hi to all! I have a problem with a nvidia geforce 520mx [NVd0 generation card (0x0d9110a1)] i have on my notebook (samsung 3 series). In practice i'm not able to use it with bumblebee and bbswitch. The dmesg message is: [ 13.507435] nouveau 0000:01:00.0: power state changed by ACPI to D0 [ 13.507440] nouveau 0000:01:00.0: power state changed by ACPI to D0 [ 13.507448] nouveau
