  spi: cadence-quadspi: fix cleanup of rx_chan on failure paths (2025-07-01 14:02:26 +0100)

----------------------------------------------------------------
spi: Fixes for v6.16

As well as a few driver specific fixes we've got a core change here
which raises the hard coded limit on the number of devices we can
support on one SPI bus since some FPGA based systems are running into
the existing limit.  This is not a good solution but it's one suitable
for this point in the release cycle, we should dynamically size the
relevant data structures which I hope will happen in the next couple of
merge windows.

We also pull in a MTD fix for the Qualcomm SNAND driver, the two fixes
cover the same issue and merging them together minimises bisection
issues.
