Subject: [PATCH v4 0/3] Convert manual kfree(dev) to put_device()
Date: Fri,  4 Sep 2026 17:16:06 +0000	[thread overview]
Message-ID: <20260904171610.3342398-1-tarunsahu@google.com> (raw)

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.

V4 <- V3
1. Added Fixes tags
2. update commit msg as per the suggestion on v3

V3 <- V2
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.
