of: use pr_fmt prefix for all console printing

2016-07-18T21:57:42Z

Clean-up all the DT printk functions to use common pr_fmt prefix. Some print statements such as kmalloc errors were redundant, so just drop those. Cc: Frank Rowand Cc: Pantelis Antoniou Reviewed-by: Frank Rowand Signed-off-by: Rob Herring

of: fix memory leak related to safe_name()

2016-06-24T20:16:10Z

Fix a memory leak resulting from memory allocation in safe_name(). This patch fixes all call sites of safe_name(). Mathieu Malaterre reported the memory leak on boot: On my PowerMac device-tree would generate a duplicate name: [ 0.023043] device-tree: Duplicate name in PowerPC,G4@0, renamed to "l2-cache#1" in this case a newly allocated name is generated by `safe_name`. However in this case it is never deallocated. The bug was found using kmemleak reported as: unreferenced object 0xdf532e60 (size 32): comm "swapper", pid 1, jiffies 4294892300 (age 1993.532s) hex dump (first 32 bytes): 6c 32 2d 63 61 63 68 65 23 31 00 dd e4 dd 1e c2 l2-cache#1...... ec d4 ba ce 04 ec cc de 8e 85 e9 ca c4 ec cc 9e ................ backtrace: [] kvasprintf+0x64/0xc8 [] kasprintf+0x4c/0x5c [] safe_name.isra.1+0x80/0xc4 [] __of_attach_node_sysfs+0x6c/0x11c [] of_core_init+0x8c/0xf8 [] kernel_init_freeable+0xd4/0x208 [] kernel_init+0x24/0x11c [] ret_from_kernel_thread+0x5c/0x64 Link: https://bugzilla.kernel.org/show_bug.cgi?id=120331 Signed-off-by: Frank Rowand Reported-by: mathieu.malaterre@gmail.com Tested-by: Mathieu Malaterre Cc: stable@vger.kernel.org Signed-off-by: Rob Herring

of: dynamic: changeset prop-update revert fix

2016-05-16T12:29:12Z

When reverting an update property changeset entry that created a property the reverse operation is a remove property and not an update. Signed-off-by: Pantelis Antoniou Signed-off-by: Rob Herring

drivers/of: Export of_detach_node()

2016-05-16T12:22:36Z

This exports of_detach_node() for PowerPC PowerNV PCI hotplug driver. No functional changes introduced. Signed-off-by: Gavin Shan Signed-off-by: Rob Herring

drivers/of: Export OF changeset functions

2016-01-13T22:10:37Z

The PowerNV PCI hotplug driver is going to use the OF changeset to manage the changed device sub-tree. This exports those OF changeset functions for that. Signed-off-by: Gavin Shan Acked-by: Wolfram Sang Tested-by: Wolfram Sang Signed-off-by: Rob Herring

of/dynamic: Fix test for PPC_PSERIES

2015-06-05T01:39:28Z

"IS_ENABLED(PPC_PSERIES)" always evaluates to false, as IS_ENABLED() is supposed to be used with the full Kconfig symbol name, including the "CONFIG_" prefix. Add the missing "CONFIG_" prefix to fix this.

of/reconfig: Always use the same structure for notifiers

2014-11-24T22:25:03Z

The OF_RECONFIG notifier callback uses a different structure depending on whether it is a node change or a property change. This is silly, and not very safe. Rework the code to use the same data structure regardless of the type of notifier. Signed-off-by: Grant Likely Cc: Benjamin Herrenschmidt Cc: Rob Herring Cc: Pantelis Antoniou Cc:

of/reconfig: Add debug output for OF_RECONFIG notifiers

2014-11-24T22:25:00Z

Add some additional debug output to cover OF_RECONFIG notifier activity. At the same time, refactor the changeset debug output to use the same strings as the notifier debug output. Signed-off-by: Grant Likely

of/reconfig: Add of_reconfig_get_state_change() of notifier helper.

2014-11-24T22:24:54Z

Introduce of_reconfig_get_state_change() which allows an of notifier to query about device state changes. Signed-off-by: Pantelis Antoniou Signed-off-by: Grant Likely

of: Refactor __of_node_alloc() into __of_node_dup()

2014-11-24T22:24:41Z

Add a node argument to __of_node_alloc() and rename it to __of_node_dup() so that it can also be used to duplicate a node with its properties. This is important for the overlay code so that it can create new nodes without using separate changeset items for every single property. At the same time rework the overlay code to use the new function and drop the extra changeset items. Signed-off-by: Grant Likely
