A while back I started the introduction of the 'spi_delay' data type:
https://lore.kernel.org/linux-spi/20190926105147.7839-1-alexandru.ardelean@…
Users of the 'delay_usecs' were removed from drivers.
Now it's time to remove the 'delay_usecs' from the SPI subsystem and use
only the 'delay' field.
This changeset adapts all SPI drivers to do without 'delay_usecs'.
Additionally, for greybus we need to adapt it to use the 'delay' in
nano-seconds and convert it to micro-seconds.
Alexandru Ardelean (10):
spi: spi-axi-spi-engine: remove usage of delay_usecs
spi: bcm63xx-spi: don't check 'delay_usecs' field
spi: spi-bcm-qspi: replace 'delay_usecs' with 'delay.value' check
spi: spi-sh: replace 'delay_usecs' with 'delay.value' in pr_debug
spi: spi-tegra20-flash: don't check 'delay_usecs' field for spi
transfer
staging: greybus: spilib: use 'spi_delay_to_ns' for getting xfer delay
spi: spi-falcon: remove check for 'delay_usecs'
spi: fsl-espi: remove usage of 'delay_usecs' field
spi: core: remove 'delay_usecs' field from spi_transfer
spi: docs: update info about 'delay_usecs'

In gb_operation_response_send, get an extra reference
before gb_message_send() with this comment "/* Reference will
be dropped when message has been sent. */". Therefore, we
should drop the got reference not only in the error branch,
but also in the complete branch.
