[PATCH 3.12 117/123] [media] gscpa_m5602: use msecs_to_jiffies for conversions

From: Jiri Slaby
Date: Wed Oct 28 2015 - 09:58:57 EST


From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit 63f2f417526fc54191f2b813f72dc1d5322bede8 upstream.

API compliance scanning with coccinelle flagged:
./drivers/media/usb/gspca/m5602/m5602_s5k83a.c:180:9-25:
WARNING: timeout (100) seems HZ dependent

Numeric constants passed to schedule_timeout() make the effective
timeout HZ dependent which makes little sense in a polling loop for
the cameras rotation state.
Fixed up by converting the constant to jiffies with msecs_to_jiffies()
