From: Randy Dunlap <rdun...@infradead.org> Fix build errors when CONFIG_HWSPINLOCK=m.
This patch fixes the build errors when COMPILE_TEST=y, but I expect that this driver also wants HWSPINLOCK_SPRD=y (or =m when SPI_SPRD_ADI=m). drivers/spi/spi-sprd-adi.o: In function `sprd_adi_remove': spi-sprd-adi.c:(.text+0x13): undefined reference to `hwspin_lock_free' drivers/spi/spi-sprd-adi.o: In function `sprd_adi_probe': spi-sprd-adi.c:(.text+0xf5): undefined reference to `of_hwspin_lock_get_id' spi-sprd-adi.c:(.text+0x107): undefined reference to `hwspin_lock_request_specific' spi-sprd-adi.c:(.text+0x22e): undefined reference to `hwspin_lock_free' drivers/spi/spi-sprd-adi.o: In function `sprd_adi_transfer_one': spi-sprd-adi.c:(.text+0x2eb): undefined reference to `__hwspin_lock_timeout' spi-sprd-adi.c:(.text+0x349): undefined reference to `__hwspin_unlock' spi-sprd-adi.c:(.text+0x389): undefined reference to `__hwspin_lock_timeout' spi-sprd-adi.c:(.text+0x3ee): undefined reference to `__hwspin_unlock' Signed-off-by: Randy Dunlap <rdun...@infradead.org> Cc: Baolin Wang <baolin.w...@spreadtrum.com> Cc: Mark Brown <broo...@kernel.org> Cc: linux-...@vger.kernel.org --- drivers/spi/Kconfig | 1 + 1 file changed, 1 insertion(+) --- linux-next-20170921.orig/drivers/spi/Kconfig +++ linux-next-20170921/drivers/spi/Kconfig @@ -625,6 +625,7 @@ config SPI_SIRF config SPI_SPRD_ADI tristate "Spreadtrum ADI controller" depends on ARCH_SPRD || COMPILE_TEST + depends on HWSPINLOCK help ADI driver based on SPI for Spreadtrum SoCs.
