Subject: vt: use msecs_to_jiffies for time conversion
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3372ec28622083ac87daf18918a222fbee06f6f9;p=linux-beck.git

vt: use msecs_to_jiffies for time conversion

Converting milliseconds to jiffies by "val * HZ / 1000" is technically
OK but msecs_to_jiffies(val) is the cleaner solution and handles all
corner cases correctly. This is a minor API consolidation only and
should make things more readable.
