Subject: IB/ehca: Use round_jiffies() for EQ polling timer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1a7d2dce4169ed42310926a5675fffd0986caa26;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

IB/ehca: Use round_jiffies() for EQ polling timer

Use round_jiffies() to align ehca's 1-second timer with other timers
and potentially save power by sleeping cores for longer.
