Subject: ncr5380: Harmonize jiffies conversion with msecs_to_jiffies
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4e5a800c82ec21335349a97cf58d97fbb0d3c98e;p=linux-beck.git

ncr5380: Harmonize jiffies conversion with msecs_to_jiffies

Instances of var * HZ / 1000 are replaced by msecs_to_jiffies(var).
In addition some timing constants that assumed HZ 100 were adjusted
to HZ independent settings based on review comments from Michael Schmitz
<schmitzmic@gmail.com> and review of the original drivers in 1.0.31 and
2.2.16.
