From d2ed4cfcd5a5d837db53466e1aeaefb1c545d4e8 Mon Sep 17 00:00:00 2001 From: Elliot Berman Date: Wed, 27 Apr 2022 12:55:25 -0700 Subject: [PATCH] ANDROID: Add flag to indicate compiling against ACK Add a flag: __ANDROID_COMMON_KERNEL__ which out-of-tree vendor drivers can use to check if they are compiling against an Android Common Kernel. These out-of-tree vendor drivers can use this flag + LINUX_KERNEL_VERSION to determine if a feature has been backported.
