watchdog: rt2880_wdt: fix return value check in rt288x_wdt_probe()
In case of error, the function devm_request_and_ioremap() returns NULL pointer not ERR_PTR(). Fix it by using devm_ioremap_resource() instead of devm_request_and_ioremap(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
