[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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
