w1: fix w1_send_slave dropping a slave id

2014-05-15T07:54:59+00:00

commit 6b355b33a64fd6d8ead2b838ec16fb9b551f71e8 upstream.

Previous logic,
if (avail > 8) {
	store slave;
	return;
}
send data; clear;

The logic error is, if there isn't space send the buffer and clear,
but the slave wasn't added to the now empty buffer loosing that slave
id.  It also should have been "if (avail >= 8)" because when it is 8,
there is space.

Instead, if there isn't space send and clear the buffer, then there is
always space for the slave id.

w1 - call request_module with w1 master mutex unlocked

2013-10-07T07:12:14+00:00

request_module for w1 slave modules needs to be called with the w1
master mutex unlocked. Because w1_attach_slave_device gets always(?)
called with mutex locked, we need to temporarily unlock the w1 master
mutex for the loading of the w1 slave module.

w1 - fix fops in w1_bus_notify

2013-10-07T07:12:14+00:00

Introduce a check to make sure that fops are only called if they have
been defined by the slave module.

Without this check modules like w1_smem cause a NULL pointer dereference
bug.

drivers/w1/masters/mxc_w1.c: remove unnecessary platform_set_drvdata()

2013-09-11T22:59:36+00:00

The driver core clears the driver data to NULL after device_release or on
probe failure.  Thus, it is not needed to manually clear the device driver
data to NULL.

drivers/w1/w1.c: replace strict_strtol() with kstrtol()

2013-09-11T22:59:35+00:00

The usage of strict_strtol() is not preferred, because strict_strtol() is
obsolete.  Thus, kstrtol() should be used.

w1: slaves: w1_ds2781: convert to use w1_family_ops.groups

2013-08-22T18:05:44+00:00

This moves the sysfs file creation/removal to the w1 core by using the
.groups field, saving code in the slave driver.
