Subject: USB: image: use msecs_to_jiffies for time conversion
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9751afbbb02d7a1c0f57191b8423948344a7ed86;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

USB: image: use msecs_to_jiffies for time conversion

This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).
