    watchdog: wm831x watchdog really needs mfd · d0e32fba
    Arnd Bergmann authored
    The wm831x watchdog driver can now be built without the wm831x mfd
    driver, which results in a link error:
    
    (.text+0x1a95c): undefined reference to `wm831x_set_bits'
    (.text+0x1a95c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `wm831x_set_bits'
    (.text+0x1a968): undefined reference to `wm831x_reg_lock'

    (.text+0x1a9dc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `wm831x_reg_unlock'
    
    This adds back the dependency that was removed. We can still build test
    this driver on all architectures by enabling the MFD driver for it first.
    
    Fixes: da2a68b3 ("watchdog: Enable COMPILE_TEST where possible")
