[PATCH v2 1/8] watchdog: watchdog_dev: Use single variable name for struct watchdog_device

2015-08-07 Thread Guenter Roeck
The current code uses 'wdd', wddev', and 'watchdog' as variable names
for struct watchdog_device. This is confusing and makes it difficult
to enhance the code. Replace it all with 'wdd'.
