Date: Mon, 18 Sep 2017 22:48:16 +0200 From: Arnd Bergmann <arnd@...db.de> To: Zhang Rui <rui.zhang@...el.com>, Eduardo Valentin <edubezval@...il.com> Cc: Leonard Crestez <leonard.crestez@....com>, Shawn Guo <shawnguo@...nel.org>, Arnd Bergmann <arnd@...db.de>, linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] 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.
