Subject: [PATCH 0/2] vsprintf Stop using obsolete simple_strtoul()
Date:   Tue, 11 Dec 2018 15:21:11 +0000

Hi,
We've fixed a bug with sscanf(). When passing in a 16-digit hex-string like so:

	sscanf("fafafafa0b0b0b0b", "%8x%8x", &hi, &lo)

The resulting value in hi is always 0. This is because vsscanf() uses the
obsolete and broken functions simple_strtoul() and simple_strtoull(), which we
have replaced.

Many thanks,
Thomas
