* string: implement strchrnulAhmad Fatoum2021-06-281-8/+0
| | | | | | | | | | We have at least two places opencoding strchrnul, one of them needlessly iterating twice instead of once over the string. Replace both by calling a common single pass implementation.

* commands/hwclock: Check return value of rtc_read_time()Andrey Smirnov2016-01-071-2/+4
| | | | | | | | | It is possible for rtc_read_time() to fill struct rtc_time it returns with invalid values, so we have to check for its return value before using returned time. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
