Subject: [PATCH -next] spi: fix spi-sprd-adi build errors when COMPILE_TEST=y

From: Randy Dunlap <rdunlap@...radead.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).
