./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)

V2: botched prefix in the subject line updated to irda: thanks
to David Miller <da...@davemloft.net>
Should the Status note at the top of the file be updated ? it seems
the file has been marked experimental since at least 1999 ?
