From e0a3862c14f80e34d5787f1e038601da8ff9cc77 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 8 Nov 2016 15:49:30 +0100 Subject: [PATCH] clk: pxa mark dummy helper as 'inline' The dummy_clk_set_parent function is marked as 'static' but is no longer referenced from the pxa25x clk driver after the last use of the RATE_RO_OPS() macro is gone from this file, causing a harmless build warning: In file included from drivers/clk/pxa/clk-pxa25x.c:24:0: drivers/clk/pxa/clk-pxa.h:146:12: error: 'dummy_clk_set_parent' defined but not used [-Werror=unused-function] This marks the functon as 'inline', which lets the compiler simply drop it when it gets referenced.
