This reverts commit1af6d1696cwhich is commit 04a8ff1bc3514808481ddebd454342ad902a3f60 upstream. There is cadence-qspi ff8d2000.spi: Unbalanced pm_runtime_enable! error without this revert. After reverting commitcdfb20e4b3("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and commit1af6d1696c("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths"), Unbalanced pm_runtime_enable! error does not appear. These two commits are backported from upstream commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and commit 04a8ff1bc351 ("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths"). The commit 04a8ff1bc351 ("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths") fix commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance"). The commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") fix commit 86401132d7bb ("spi: spi-cadence-quadspi: Fix missing unwind goto warnings"). The commit 86401132d7bb ("spi: spi-cadence-quadspi: Fix missing unwind goto warnings") fix commit 0578a6dbfe75 ("spi: spi-cadence-quadspi: add runtime pm support"). 6.6.y only backport commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and commit 04a8ff1bc351 ("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths"), but does not backport commit 0578a6dbfe75 ("spi: spi-cadence-quadspi: add runtime pm support") and commit 86401132d7bb ("spi: spi-cadence-quadspi: Fix missing unwind goto warnings"). And the backport of commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") differs with the original patch. So there is Unbalanced pm_runtime_enable error. If revert the backport for commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and commit 04a8ff1bc351 ("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths"), there is no error. If backport commit 0578a6dbfe75 ("spi: spi-cadence-quadspi: add runtime pm support") and commit 86401132d7bb ("spi: spi-cadence-quadspi: Fix missing unwind goto warnings"), there is hang during booting. I didn't find the cause of the hang. Since commit 0578a6dbfe75 ("spi: spi-cadence-quadspi: add runtime pm support") and commit 86401132d7bb ("spi: spi-cadence-quadspi: Fix missing unwind goto warnings") are not backported, commit b07f349d1864 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and commit 04a8ff1bc351 ("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths") are not needed. So revert commits commitcdfb20e4b3("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and commit1af6d1696c("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths").

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.
