dvb: l64781.ko broken with gcc 4.5
Commit Message
From: Richard Guenther <rguenther@suse.de>
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.
