From 10d3340441bd0db857fc7fcb1733a800acf47a3d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 19 Jul 2023 11:02:23 +0200 Subject: mfd: rz-mtu3: Link time dependencies The new set of drivers for RZ/G2L MTU3a tries to enable compile-testing the individual client drivers even when the MFD portion is disabled but gets it wrong, causing a link failure when the core is in a loadable module but the other drivers are built-in: x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply': pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write' x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable' arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get': rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read' It seems better not to add the extra complexity here but instead just use a normal hard dependency, so remove the #else portion in the header along with the "|| COMPILE_TEST". This could also be fixed by having slightly more elaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper, but in practice it's already possible to compile-test all these drivers by enabling the mtd portion.
