Date: Tue, 3 Feb 2015 03:45:11 -0500 From: Nicholas Mc Guire <hofrat@...dl.org> To: Samuel Chessman <chessman@....org> Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Nicholas Mc Guire <hofrat@...dl.org> Subject: [PATCH 2/2] tlan: msecs_to_jiffies convrsion This is only an API consolidation and should make things more readable it replaces var * HZ / 1000 by msecs_to_jiffies(var). As there is a discrepancy between the code and the comments this is in a separate patch. Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org> --- Converting milliseconds to jiffies by val * HZ / 1000 is technically not wrong but msecs_to_jiffies(val) is the cleaner solution and handles all corner cases correctly. This basically is a minor API cleanup only but the comment and the code do not match ! Comments states "do the longer, just in case" which would be 500 ms - the code though sets it to HZ/20 == 50ms. This needs a review by someone that knows the driver details to decide if it should be 50 or 500ms here. Patch was only compile tested for x86_64_defconfig + CONFIG_TLAN=m Patch is against 3.0.19-rc7 (localversion = -next-20150203) drivers/net/ethernet/ti/tlan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ethernet/ti/tlan.c b/drivers/net/ethernet/ti/tlan.c index 1f722c9..691ec93 100644 --- a/drivers/net/ethernet/ti/tlan.c +++ b/drivers/net/ethernet/ti/tlan.c @@ -2561,7 +2561,7 @@ static void tlan_phy_power_up(struct net_device *dev) * transceiver.
