[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

[PATCH 00/13] Convert all users of strlcpy to strscpy

by Kumar Kartikeya Dwivedi

This series converts all existing users of strlcpy in drivers/staging to use strscpy instead. strlcpy is marked as deprecated in Documentation/process/deprecated.rst, and there is no functional difference when the caller expects truncation (when not checking the return value). strscpy is relatively better as it also avoids scanning the whole source string. This silences the related checkpatch warnings from: 5dbdb2d87c29 ("checkpatch: prefer strscpy to strlcpy") The conversions were performed in two steps: 1. The following coccinelle script was used to identify and replace call sites that expect truncation. $ spatch --sp-file strscpy.cocci --include-headers --dir --in-place drivers/staging @strscpy@ expression dest, src, size; @@ -strlcpy(dest, src, size); +strscpy(dest, src, size); 2. Each individual automated conversion was rechecked manually for correctness.
