[PATCH 1/4] ARM: shmobile: rcar-gen2: Make rcar_gen2_dma_contiguous static
From: Simon Horman <hidden>
Date: 2016-02-04 14:29:32
Subsystem:
arm port, arm/risc-v/renesas architecture, the rest · Maintainers:
Russell King, Geert Uytterhoeven, Magnus Damm, Linus Torvalds
From: Geert Uytterhoeven <geert+renesas@glider.be>
make C=1:
arch/arm/mach-shmobile/setup-rcar-gen2.c:186:12: warning: symbol 'rcar_gen2_dma_contiguous' was not declared. Should it be static?
Make it static, and move it inside the function to avoid a "defined but
not used" warning if CONFIG_DMA_CMA=n.
