From 524bcbb494d5486470b993d7d717234d5781da03 Mon Sep 17 00:00:00 2001 From: Andrew McRae Date: Thu, 19 Sep 2019 16:55:52 +1000 Subject: drivers/wifi/generic.c: Upper case the AML WiFi name as required by spec ACPI 6.3, ASL 20.2.2 (Name Objects Encoding) states: LeadNameChar := 'A'-'Z' | '_' NameChar := DigitChar | LeadNameChar Hence, the Intel WiFi names generated in ASL are required to be upper-cased letters. BUG=b:141206986 TEST=Reflash and confirmed SSDT table has correct name.
