The dependency was clearly needed, without it it is possible to build the core i2c driver as a loadable module and the bq27xxx driver built-in, which results in link errors: drivers/built-in.o: In function `bq27xxx_battery_i2c_read': binder.c:(.text+0x360bf0): undefined reference to `i2c_transfer' binder.c:(.text+0x360c10): undefined reference to `i2c_transfer' drivers/built-in.o: In function `bq27xxx_battery_init': binder.c:(.init.text+0xe668): undefined reference to `i2c_register_driver' drivers/built-in.o: In function `bq27xxx_battery_exit': binder.c:(.exit.text+0x1a0c): undefined reference to `i2c_del_driver' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 6bd03ce3c12a ("power: bq27xxx_battery: Remove unneeded dependency in Kconfig") --- The bug was originally found and fixed by Xiong Zhou, but Andrew Davis broke it again by reverting the fix.
