rtc: fix snprintf() checking in is_rtc_hctosys()

2021-07-20T14:10:51Z

[ Upstream commit 54b909436ede47e0ee07f1765da27ec2efa41e84 ] The scnprintf() function silently truncates the printf() and returns the number bytes that it was able to copy (not counting the NUL terminator). Thus, the highest value it can return here is "NAME_SIZE - 1" and the overflow check is dead code. Fix this by using the snprintf() function which returns the number of bytes that would have been copied if there was enough space and changing the condition from "> NAME_SIZE" to ">= NAME_SIZE".
