a110f93d8b spi: quad: fix the name of DT property
spi: quad: fix the name of DT property in patch

The previous property name spi-tx-nbits and spi-rx-nbits looks not
human-readable. To make it consistent with other devices, using property
name spi-tx-bus-width and spi-rx-bus-width instead of the previous one
specify the number of data wires that spi controller will work in.
Add the specification in spi-bus.txt.

e93b07244d spi: core: Fix spi_register_master error handling
In the case spi_master_initialize_queue() fails, current code calls
device_unregister() before return error from spi_register_master().
However, all the drivers call spi_master_put() in the error path if
spi_register_master() fails. Thus we should call device_del() rather than
device_unregister() before return error from spi_register_master().

This also makes all the spi_register_master() error handling consistent,
because all other error paths of spi_register_master() expect drivers to
call spi_master_put() if spi_register_master() fails.

f073d37de0 spi: altera: Use DIV_ROUND_UP to calculate hw->bytes_per_word
The Altera SPI hardware can be configured to support data width from 1 to 32
since Quartus II 8.1. To avoid truncation by integer division, use DIV_ROUND_UP
to calculate hw->bytes_per_word.

9d3405dbbb spi: rspi: Add spi_master_get() call to prevent use after free
In rspi_remove(), current code dereferences rspi after spi_unregister_master(),
thus add an extra spi_master_get() call is necessary to prevent use after free.

Current code already has an extra spi_master_put() call in rspi_remove(), so
this patch just adds a spi_master_get() call rather than a spi_master_get() with
spi_master_put() calls.

a822e99c70 spi: quad: Make DT properties optional
The addition SPI quad support made the DT properties mandatory, breaking
compatibility with existing systems. Fix that by making them optional,
also improving the error messages while we're at it.
