irda: use msecs_to_jiffies for conversion to jiffies
API compliance scanning with coccinelle flagged: ./net/irda/timer.c:63:35-37: use of msecs_to_jiffies probably perferable Converting milliseconds to jiffies by "val * HZ / 1000" technically is not a clean solution as it does not handle all corner cases correctly. By changing the conversion to use msecs_to_jiffies(val) conversion is correct in all cases. Further the () around the arithmetic expression was dropped. Patch was compile tested for x86_64_defconfig + CONFIG_IRDA=m Patch is against 4.1-rc4 (localversion-next is -next-20150522) Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: David S.
