mmc: mmc_spi: Fix mmc_spi_dma_alloc() return type for !HAS_DMA
If CONFIG_NO_DMA=y (e.g. Sun-3 allmodconfig): drivers/mmc/host/mmc_spi.c:1323:15: warning: return type defaults to ‘int’ [-Wreturn-type] static inline mmc_spi_dma_alloc(struct mmc_spi_host *host) { return 0; } ^~~~~~~~~~~~~~~~~ Fix this by adding the missing return type. Fixes: a395acf0f6dc6409 ("mmc: mmc_spi: Allow the driver to be built when CONFIG_HAS_DMA is unset") Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Link: https://lore.kernel.org/r/20200914094243.3912-1-geert@linux-m68k.org Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
