Subject: [PATCH v2 1/9] PM / Domains: Drop extern declarations of functions in pm_domain.h
Date: Tue, 29 May 2018 12:04:13 +0200	[thread overview]
Message-ID: <20180529100421.31022-2-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20180529100421.31022-1-ulf.hansson@linaro.org>

Using "extern" to declare a function in a public header file is somewhat
pointless, but also doesn't hurt. However, to make all the function
declarations in pm_domain.h to be consistent, let's drop the use of
"extern".
