Add suffix ULL to constant 10 in order to give the compiler complete information about the proper arithmetic to use. Notice that this constant is used in a context that expects an expression of type u64 (64 bits, unsigned). The expression fpxin = state->config->xin * 10 is currently being evaluated using 32-bit arithmetic. Addresses-Coverity-ID: 200604 Signed-off-by: Gustavo A. R. Silva <gustavo@xxxxxxxxxxxxxx> --- Changes in v2: - Update subject and changelog to better reflect the proposed code changes. - Add suffix ULL to constant instead of casting a variable. drivers/media/dvb-frontends/ves1820.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/dvb-frontends/ves1820.c b/drivers/media/dvb-frontends/ves1820.c index 1d89792..1760098 100644 --- a/drivers/media/dvb-frontends/ves1820.c +++ b/drivers/media/dvb-frontends/ves1820.c @@ -137,7 +137,7 @@ static int ves1820_set_symbolrate(struct ves1820_state *state, u32 symbolrate) NDEC = 3; /* yeuch! */ - fpxin = state->config->xin * 10; + fpxin = state->config->xin * 10ULL; fptmp = fpxin; do_div(fptmp, 123); if (symbolrate < fptmp) SFIL = 1; -- 2.7.4
