From b0ddc5b170058a9ed3c9f031501d735a4eb8ee89 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 22 Apr 2021 17:15:21 +0200 Subject: rtc: bd70528: fix BD71815 watchdog dependency The added Kconfig dependency is slightly incorrect, which can lead to a link failure when the watchdog is a loadable module: arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_set_rtc_based_timers': rtc-bd70528.c:(.text+0x6cc): undefined reference to `bd70528_wdt_set' arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_set_time': rtc-bd70528.c:(.text+0xaa0): undefined reference to `bd70528_wdt_lock' arm-linux-gnueabi-ld: rtc-bd70528.c:(.text+0xab8): undefined reference to `bd70528_wdt_unlock' arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_alm_enable': rtc-bd70528.c:(.text+0xfc0): undefined reference to `bd70528_wdt_lock' arm-linux-gnueabi-ld: rtc-bd70528.c:(.text+0x1030): undefined reference to `bd70528_wdt_unlock' The problem is that it allows to be built-in if MFD_ROHM_BD71828 is built-in, even when the watchdog is a loadable module. Rework this so that having the watchdog as a loadable module always forces the rtc to be a module as well instead of built-in, regardless of bd71828.
