From f1de1c7803595e937ce9b922807f499851225021 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Mon, 5 Jul 2021 14:57:08 +0200 Subject: media: atmel: fix build when ISC=m and XISC=y Building VIDEO_ATMEL_ISC as module and VIDEO_ATMEL_XISC as built-in (or viceversa) causes build errors: or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o: in function `isc_async_complete': atmel-isc-base.c:(.text+0x40d0): undefined reference to `__this_module' or1k-linux-ld: atmel-isc-base.c:(.text+0x40f0): undefined reference to `__this_module' or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(.rodata+0x390): undefined reference to `__this_module' or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x4): undefined reference to `__this_module' or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x18): undefined reference to `__this_module' This is caused by the file atmel-isc-base.c which is common code between the two drivers. The solution is to create another Kconfig symbol that is automatically selected and generates the module atmel-isc-base.ko. This module can be loaded when both drivers are modules, or built-in when at least one of them is built-in.
