During probe the driver allocates dummy I2C device for companion chip with i2c_new_dummy() but it does not check the return value of this call. In case of error (i2c_new_device(): memory allocation failure or I2C address cannot be used) this function returns NULL which is later used by regmap_init_i2c(). If i2c_new_dummy() fails for companion device, fail also the probe for main MFD driver. Cc: stable@vger.kernel.org Signed-off-by:

During probe the driver allocates dummy I2C device for companion chip and then allocates a regmap for it. If regmap_init_i2c() fails then the I2C driver (allocated with i2c_new_dummy()) is not freed and this resource leaks. Cc: stable@vger.kernel.org Signed-off-by:

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by:

The TPS65218 chip is a power management IC for Portable Navigation Systems and Tablet Computing devices. It contains the following components: - Regulators. - Over Temperature warning and Shut down. This patch adds support for tps65218 mfd device. At this time only the regulator functionality is made available. Signed-off-by:

This changes the following mechanisms in the TC3589x device tree probing path: - Use the .of_match_table in struct device_driver to match the device in the device tree. - Add matches for the proper compatible strings "toshiba,..." and all sub-variants, just as is done for the .id matches. - Move over all the allocation of platform data etc to the tc3589x_of_probe() function and follow the pattern of passing a platform data pointer back, or an error pointer on error, as found in the STMPE driver. - Match the new (proper) compatible strings for the GPIO and keypad MFD cells. - Use of_device_is_compatible() rather than just !strcmp() to discover which cells to instantiate.

Add of_compatible ("maxim,max14577-muic") to the mfd_cell for extcon driver. If entry with such compatible is present in the DTS, the extcon driver will have of_node set. This may be useful for extcon consumers and it is documented in bindings documentation. Signed-off-by: -

It is currently not possible to select the SA1100 or Vexpress drivers in the MFD subsystem, because the menu for the entire subsystem ends before these options are presented. Move the main menu closing and the endif for HAS_IOMEM to the end of the file so these are selectable again. Cc: stable@vger.kernel.org Signed-off-by:
