Snyder Date: Thu, 27 May 2010 17:58:44 +0000 (+0200) Subject: hwmon: (lm90) Use programmed update rate X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8c3c7a256f7ab142dfbcee2d8633dbce5a36fde7;p=linux-beck.git hwmon: (lm90) Use programmed update rate The lm90 driver programs the sensor chip to update its readings at 2 Hz (500 ms between readings). However, the driver only does reads from the chip at intervals of 2 * HZ (2000 ms between readings). Change the driver update rate to the programmed update rate. Signed-off-by: Ira W.
