    Guenter Roeck authored
    Use device managed functions to simplify error handling, reduce
    source code size, improve readability, and reduce the likelyhood of bugs.
    Other improvements as listed below.
    
    The conversion was done automatically with coccinelle using the
    following semantic patches. The semantic patches and the scripts
    used to generate this commit log are available at
    https://github.com/groeck/coccinelle-patches
    
    - Drop assignments to otherwise unused variables
    - Drop empty remove function
    - Use devm_add_action_or_reset() for calls to clk_disable_unprepare
    - Replace 'goto l; ... l: return e;' with 'return e;'
    - Introduce local variable 'struct device *dev' and use it instead of
      dereferencing it repeatedly
    - Use devm_watchdog_register_driver() to register watchdog device
    - Replace shutdown function with call to watchdog_stop_on_reboot()
