stm32_spi_remove() accesses the driver's private data after calling spi_unregister_master() even though that function releases the last reference on the spi_master and thereby frees the private data. Fix by switching over to the new devm_spi_alloc_master() helper which keeps the private data accessible until the driver has unbound.

Merge series "spi: Adding support for software nodes" from Heikki Krogerus <heikki.krogerus@linux.intel.com>: Hi, The older API used to supply additional device properties for the devices - so mainly the function device_add_properties() - is going to be removed. The reason why the API will be removed is because it gives false impression that the properties are assigned directly to the devices, which has actually never been the case - the properties have always been assigned to a software fwnode which was then just directly linked with the device when the old API was used. By only accepting device properties instead of complete software nodes, the subsystems remove any change of taking advantage of the other features the software nodes have. The change that is required from the spi subsystem and the drivers is trivial. Basically only the "properties" member in struct spi_board_info, which was a pointer to struct property_entry, is replaced with a pointer to a complete software node. thanks, Heikki Krogerus (4): spi: Add support for software nodes ARM: pxa: icontrol: Constify the software node ARM: pxa: zeus: Constify the software node spi: Remove support for dangling device properties arch/arm/mach-pxa/icontrol.c | 12 ++++++++---- arch/arm/mach-pxa/zeus.c | 6 +++++- drivers/spi/spi.c | 21 ++++++--------------- include/linux/spi/spi.h | 7 +++---- 4 files changed, 22 insertions(+), 24 deletions(-) -- 2.30.1 base-commit: a38fd874

Merge series "spi: finalize 'delay_usecs' removal/transition" from Alexandru Ardelean <aardelean@deviqon.com>: A while back I started the introduction of the 'spi_delay' data type: https://lore.kernel.org/linux-spi/20190926105147.7839-1-alexandru.ardelean@analog.com/ 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.

The 'delay' field in the spi_transfer struct is meant to replace the 'delay_usecs' field. However some cleanup was required to remove the uses of 'delay_usecs'. Now that it's been cleaned up, we can remove it from the kernel tree. Signed-off-by:

Alexandru Ardelean authored
The intent is the removal of the 'delay_usecs' field from the spi_transfer struct, as there is a 'delay' field that does the same thing. The spi_delay_to_ns() can be used to get the transfer delay. It works by using the 'delay_usecs' field first (if it is non-zero), and finally uses the 'delay' field. Since the 'delay_usecs' field is going away, this change makes use of the spi_delay_to_ns() function. This also means dividing the return value of the function by 1000, to convert it to microseconds. To prevent any potential faults when converting to microseconds and since the result of spi_delay_to_ns() is int, the delay is being computed in 32 bits and then clamped between 0 & U16_MAX.
