linux-toradex.git/net/irda, branch v4.2.6 Linux kernel for Apalis and Colibri modules irda: use msecs_to_jiffies for conversion to jiffies 2015-05-25T21:46:21+00:00 Nicholas Mc Guire hofrat@osadl.org 2015-05-25T06:16:50+00:00 005e8709c6179b75830971efa891c7ed33e02d1e 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.

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)
