This series also performs a bunch of small, rather trivial code cleanups, to make the code neater and a bit easier to read. Changes in v3: - Fixed a couple of rather embarrassing issues in patch 4/5 pointed out by the kernel test robot, [7] one of them using the va_copy() workaround approach already established in the commit 3fbcf75bb41a ("efi/printf: Factor out width/precision parsing"), but all this really made me think how didn't I notice those issues myself before sending the patches, which perhaps slipped by because I didn't take the specifics of x86_64 into account :/ - Added a somewhat lengthy comment to patch 4/5, to explain the newly introduced va_copy() workaround, partially reusing the comment found in the above-mentioned commit 3fbcf75bb41a - Added underscores to the name of the "worker" function in patch 4/5, to additionally emphasize its internal nature - Adjusted some of the variable names in patch 4/5 a bit to use what are seemingly more commonly used names Changes in v2: - Collected three Reviewed-by tags from Heiko [1][2][3] - Dropped patch 3/5, [4] as suggested by Mark, [5] improved the check to use dev_err_probe() and folded that into new patch 5/5 - Added new patch 4/5 that introduces function dev_warn_probe() that produces warnings in probe paths, to avoid the promotion of logged messages from warnings to errors, as noted by Heiko [6] - Adjusted the description of the series and of the individual patches a bit to reflect the changes, where appropriate Link to v2: https://lore.kernel.org/linux-rockchip/cover.1727496560.git.dsimic@manjaro.org/T/#u Link to v1: https://lore.kernel.org/linux-rockchip/cover.1727337732.git.dsimic@manjaro.org/T/#u [1] https://lore.kernel.org/linux-rockchip/6085918.31tnzDBltd@phil/ [2] https://lore.kernel.org/linux-rockchip/2285557.3ZeAukHxDK@phil/ [3] https://lore.kernel.org/linux-rockchip/10409403.0AQdONaE2F@phil/ [4] https://lore.kernel.org/linux-rockchip/ce2e7f90e62b15adc2bed1f53122ad39c3a9b5ac.1727337732.git.dsimic@manjaro.org/ [5] https://lore.kernel.org/linux-rockchip/ZvUmk48R4hZYlO71@finisterre.sirena.org.uk/ [6] https://lore.kernel.org/linux-rockchip/6673004.tM3a2QDmDi@phil/ [7] https://lore.kernel.org/linux-rockchip/202409290910.55WdSCMH-lkp@intel.com/ Dragan Simic (5): spi: rockchip: Perform trivial code cleanups spi: rockchip-sfc: Perform trivial code cleanups spi: rockchip-sfc: Use dev_err_probe() in the probe path driver core: Add device probe log helper dev_warn_probe() spi: rockchip: Use dev_{err,warn}_probe() in the probe path drivers/base/core.c | 129 ++++++++++++++++++++++++++------- drivers/spi/spi-rockchip-sfc.c | 21 ++---- drivers/spi/spi-rockchip.c | 55 +++++++------- include/linux/dev_printk.h | 1 + 4 files changed, 135 insertions(+), 71 deletions(-)
