commit135c6eb27aupstream. Under the conditions that a device is to be reinitialized within ufshcd_probe_hba(), the device must first be fully reset. Resetting the device should include freeing U8 model (member of dev_info) but does not, and this causes a memory leak. ufs_put_device_desc() is responsible for freeing model. unreferenced object 0xffff3f63008bee60 (size 32): comm "kworker/u33:1", pid 60, jiffies 4294892642 hex dump (first 32 bytes): 54 48 47 4a 46 47 54 30 54 32 35 42 41 5a 5a 41 THGJFGT0T25BAZZA 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc ed7ff1a9): [<ffffb86705f1243c>] kmemleak_alloc+0x34/0x40 [<ffffb8670511cee4>] __kmalloc_noprof+0x1e4/0x2fc [<ffffb86705c247fc>] ufshcd_read_string_desc+0x94/0x190 [<ffffb86705c26854>] ufshcd_device_init+0x480/0xdf8 [<ffffb86705c27b68>] ufshcd_probe_hba+0x3c/0x404 [<ffffb86705c29264>] ufshcd_async_scan+0x40/0x370 [<ffffb86704f43e9c>] async_run_entry_fn+0x34/0xe0 [<ffffb86704f34638>] process_one_work+0x154/0x298 [<ffffb86704f34a74>] worker_thread+0x2f8/0x408 [<ffffb86704f3cfa4>] kthread+0x114/0x118 [<ffffb86704e955a0>] ret_from_fork+0x10/0x20 Fixes:96a7141da3("scsi: ufs: core: Add support for reinitializing the UFS device") Cc: <stable@vger.kernel.org> Reviewed-by: Andrew Halaney <ahalaney@redhat.com> Reviewed-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Joel Slebodnick <jslebodn@redhat.com> Link: https://lore.kernel.org/r/20240613200202.2524194-1-jslebodn@redhat.com Signed-off-by: Martin K.

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.
