[PATCH] greybus: remove stray nul byte in apb_log_enable_read output

by Rasmus Villemoes

Including a nul byte in the otherwise human-readable ascii output from this debugfs file is probably not intended.

[PATCH 00/10] spi: finalize 'delay_usecs' removal/transition

by Alexandru Ardelean

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' Documentation/spi/spi-summary.rst | 7 +++++-- drivers/spi/spi-axi-spi-engine.c | 12 ++++-------- drivers/spi/spi-bcm-qspi.c | 2 +- drivers/spi/spi-bcm63xx.c | 2 +- drivers/spi/spi-falcon.c | 2 +- drivers/spi/spi-fsl-espi.c | 17 +++++------------ drivers/spi/spi-sh.c | 4 ++-- drivers/spi/spi-tegra20-sflash.c | 3 +-- drivers/spi/spi.c | 1 - drivers/staging/greybus/spilib.c | 5 ++++- include/linux/spi/spi.h | 12 ------------ 11 files changed, 24 insertions(+), 43 deletions(-) -- 2.29.2

[PATCH v2] greybus/operation: Drop reference when message has been sent

by Lv Yunlong

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.
