07f1eb718dUse devm_pm_runtime_enable(), devm_request_irq() and devm_spi_register_controller() to simplify code. And also register a callback spi_geni_release_dma_chan() with devm_add_action_or_reset(), to release dma channel in both error and device detach path, which can make sure the release sequence is consistent with the original one. 1. Unregister spi controller. 2. Free the IRQ. 3. Free DMA chans 4. Disable runtime PM. So the remove function can also be removed.

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 reStructuredText 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.
