[ Upstream commit5b79480ce1] If device_add() succeeds, we should call device_del() when want to get rid of it, so move it into proper jump symbol. Otherwise, when __power_supply_register() returns fail and goto wakeup_init_failed to exit, there is still residue device file in sysfs. When attempt to probe device again, sysfs would complain as below: sysfs: cannot create duplicate filename '/devices/platform/i2c/i2c-0/0-001c/power_supply/adp5061' Call Trace: dump_stack_lvl+0x68/0x85 sysfs_warn_dup.cold+0x1c/0x29 sysfs_create_dir_ns+0x1b1/0x1d0 kobject_add_internal+0x143/0x390 kobject_add+0x108/0x170 Fixes:80c6463e2f("power_supply: Fix Oops from NULL pointer dereference from wakeup_source_activate") Signed-off-by: Zeng Heng <zengheng4@huawei.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
