From e83f374247c310bc558c8626fbfcc03f22f9bf02 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 5 Oct 2017 22:39:37 +0200 Subject: [PATCH] spi: spreadtrum adi: add hwspinlock dependency With CONFIG_HWSPINLOCK=m, the new driver fails to link as a built-in driver: drivers/spi/spi-sprd-adi.o: In function `sprd_adi_remove': spi-sprd-adi.c:(.text+0x18): undefined reference to `hwspin_lock_free' drivers/spi/spi-sprd-adi.o: In function `sprd_adi_probe': spi-sprd-adi.c:(.text+0xfc): undefined reference to `of_hwspin_lock_get_id' spi-sprd-adi.c:(.text+0x108): undefined reference to `hwspin_lock_request_specific' spi-sprd-adi.c:(.text+0x268): undefined reference to `hwspin_lock_free' This adds a hard Kconfig dependency on HWSPINLOCK for the !COMPILE_TEST case, and allows compile-testing with HWSPINLOCK completely disabled, which will then rely on the existing stub API.
