[PATCH v3 0/3] Convert manual kfree(dev) to put_device()

From: Tarun Sahu <hidden>

Also in: driver-core, linux-arm-kernel, lkml

Hello,

As per the kernel-doc guidelines, Devices that are tried to register
with device_register or to add using device_add, must use put_device
on their failure path (not kfree). This series contains 3 patches
for updating such instances. Same for kobject_init_and_add or
kobject_add, call kobject_put instead of kfree in case of error.

V3<-V1
1. Updated the commit msg of each patch to mention about the kernel-doc
   guidelines.

V2 <- V1
1. Removed patch [1] as it is part of another series [2] already.
