From 397e2f66a23469e2b8a13b764cb2d9ff2444ad5a Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 12 Jun 2006 21:49:36 +0200 Subject: [PATCH] [PATCH] i2c-i801: Fix block transaction poll loops i2c-i801: Fix block transaction poll loops Two of the three poll loops have the poll and sleep swapped, causing an extra sleep to occur after the polled condition is fulfilled. In practice, this doubles the amount of sleep time for every block transaction.
