From c1db53b36633e6a7511dbec7c372f01a31528f0c Mon Sep 17 00:00:00 2001 From: Richard Guenther Date: Tue, 9 Feb 2010 20:16:03 -0300 Subject: [PATCH] V4L/DVB: dvb: l64781.ko broken with gcc 4.5 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.
