#     hex2bin: fix access beyond string end
#     
#     If we pass too short string to "hex2bin" (and the string size without
#     the terminating NUL character is even), "hex2bin" reads one byte after
#     the terminating NUL character.  This patch fixes it.
#     
#     Note that hex_to_bin returns -1 on error and hex2bin return -EINVAL on
#     error - so we can't just return the variable "hi" or "lo" on error.
#     This inconsistency may be fixed in the next merge window, but for the
#     purpose of fixing this bug, we just preserve the existing behavior and
#     return -1 and -EINVAL.
