Currrently the memory for the clk_bulk_data of the QSPI controller is allocated with spi_alloc_master(). The bulk data pointer is passed to devm_clk_bulk_get() which saves it in clk_bulk_devres->clks. When the device is removed later devm_clk_bulk_release() is called and uses the bulk data referenced by the pointer to release the clocks. For this driver this results in accessing memory that has already been freed, since the memory allocated with spi_alloc_master() is released by spi_controller_release(), which is called before the managed resources are released. Use device managed memory for the clock bulk data to fix the issue described above.

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.
