From a16130569af7e92b0a68a8c96170d84756f91c47 Mon Sep 17 00:00:00 2001 From: David Fries Date: Wed, 15 Jan 2014 22:29:15 -0600 Subject: w1: increase w1_max_slave_count, allow write access w1_max_slave_count is only used to abort the search early or take a fast search (when 1), so there isn't any reason to not allow it to be updated through sysfs. Memory is not allocated based on the current value and 10 is a rather low base number, increasing to 64, and printing a message the first time the count is reached and there were more devices to discover to let the user know why not all the devices were found.
