Revert "spi: cadence-quadspi: fix cleanup of rx_chan on failure paths"

Browse Source 
This reverts commit 1af6d1696c which is
commit 04a8ff1bc3514808481ddebd454342ad902a3f60 upstream.

There is cadence-qspi ff8d2000.spi: Unbalanced pm_runtime_enable! error
without this revert.

After reverting commit cdfb20e4b3 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance")
and commit 1af6d1696c ("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 commit cdfb20e4b3 ("spi: spi-cadence-quadspi: Fix pm runtime unbalance") and
commit 1af6d1696c ("spi: cadence-quadspi: fix cleanup of rx_chan on failure paths").
