V4L/DVB: dvb: l64781.ko broken with gcc 4.5
commit c1db53b36633e6a7511dbec7c372f01a31528f0c upstream.
I'm trying to fix it on the GCC side (PR43007), but the module is
quite stupid in using ULL constants to operate on u32 values:
static int apply_frontend_param (struct dvb_frontend* fe, struct
dvb_frontend_parameters *param)
{
...
static const u32 ppm = 8000;
u32 spi_bias;
...
spi_bias *= 1000ULL;
spi_bias /= 1000ULL + ppm/1000;
which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again.
This patch fixes this issue.
