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 Signed-off-by: David S.
