In commitbbc4e7d273("i40e: fix race condition with PTP_TX_IN_PROGRESS bits") we modified the code which handles Tx timestamps so that we would clear the progress bit as soon as possible. A later commit0bc0706b46("i40e: check for Tx timestamp timeouts during watchdog") introduced similar code for detecting and handling cleanup of a blocked Tx timestamp. This code did not use the same pattern for cleaning up the skb. Update this code to wait to free the skb until after the bit lock is free, by first setting the ptp_tx_skb to NULL and clearing the lock.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
