[ Upstream commit 6eaafbb6998e999467cf78a76e155ee00e372b14 ] IAD Register is yet readable trough the "iad" sys file. A write to the "iad" sys file enables or disables the current measurement, but it was not possible to get the measured value by reading it. Fix: %u in snprintf for unsigned values (vdd and vad) Fix: Avoid possibles overflows (Usage of the 'count' variables) Signed-off-by: Julien Folly <julien.folly@gmail.com> Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
