Use of time_after() macro, defined at linux/jiffies.h, which deal with
wrapping correctly and are nicer to read.

I think these both should be
if (time_before(jiffies, dev->trans_start + HZ))
Thanks,

Again, following Nish's catch, now the patch is using time_before()
macro, instead of time_after() macro,
that was the way I did before. Both macros are defined at
linux/jiffies.h. Any problem, please contact-me.
