This is a nonfunctional change, declare register bit values with BIT() helper macro. The issues are reported by checkpatch: CHECK: Prefer using the BIT macro #40: FILE: drivers/watchdog/imx2_wdt.c:40: +#define IMX2_WDT_WCR_WDA (1 << 5) /* -> External Reset WDOG_B */ etc. Signed-off-by: Vladimir Zapolskiy <vladimir_zapolskiy@mentor.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
