V4L/DVB (13107): tda18271: fix overflow in FM radio frequency calculation commit 4d8317876d5f53ef792e90f89d8f162d7bca5c81 upstream. Multiplication by 62500 causes an overflow in the 32 bit freq variable, which is later divided by 1000 when using FM radio. This patch prevents the overflow by scaling the frequency value correctly upfront. Thanks to Henk Vergonet for spotting the problem and providing a preliminary patch, which this changeset was based upon.
