drivers/net/hamradio: Integer overflow in hdlcdrv_ioctl()
[ Upstream commit e9db5c21d3646a6454fcd04938dd215ac3ab620a ]
The local variable 'bi' comes from userspace. If userspace passed a
large number to 'bi.data.calibrate', there would be an integer overflow
in the following line:
s->hdlctx.calibrate = bi.data.calibrate * s->par.bitrate / 16;
