Different platforms have different Master with different SourceID on
AHB bus. The 0X0E Master ID is used by cluster 3 in case of LS2088A.
So, patch introduce an invalid master id variable to fix invalid
mastered on different platforms.

The patch
spi: spi-fsl-qspi: Introduce variable to fix different invalid master Id
has been applied to the spi tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.5
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

Subject: [PATCH] spi: spi-fsl-qspi: Introduce variable to fix different
invalid master Id
Different platforms have different Master with different SourceID on
AHB bus. The 0X0E Master ID is used by cluster 3 in case of LS2088A.
So, patch introduce an invalid master id variable to fix invalid
mastered on different platforms.
