From: Arnd Bergmann Date: Mon, 18 Sep 2017 20:48:16 +0000 (+0200) Subject: thermal: imx: add NVMEM dependency X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=531fcdeb71f0be1d4c77838b1a4694c317b1eb98;p=linux.git thermal: imx: add NVMEM dependency The driver now fails to link into vmlinux when CONFIG_NVMEM is a loadable module: drivers/thermal/imx_thermal.o: In function `imx_thermal_probe': imx_thermal.c:(.text+0x360): undefined reference to `nvmem_cell_read_u32' imx_thermal.c:(.text+0x360): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `nvmem_cell_read_u32' imx_thermal.c:(.text+0x388): undefined reference to `nvmem_cell_read_u32' imx_thermal.c:(.text+0x388): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `nvmem_cell_read_u32' This adds a Kconfig dependency to force it to be a module as well when its dependency is loadable.
