Subject: checkpatch: add check for keyword 'boolean' in Kconfig definitions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=327953e9af6c59ad111b28359e59e3ec0cbd71b6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

checkpatch: add check for keyword 'boolean' in Kconfig definitions

Discourage the use of keyword 'boolean' for type definition attributes of
config options as support for it will be dropped later on.
