of: base: use strscpy() to instead of strncpy()

2023-01-06T03:23:14Z

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings. Signed-off-by: Xu Panda Signed-off-by: Yang Yang Link: https://lore.kernel.org/r/202212231039128402297@zte.com.cn Signed-off-by: Rob Herring

of: base: Shift refcount decrement in of_find_last_cache_level()

2022-10-03T16:21:37Z

Currently, of_find_next_cache_node() and of_property_read_u32() are called on objects after their refcount have been decremented. Re-order the calls to decrement the refcount after the function calls.

of: base: export of_device_compatible_match() for use in modules

2022-08-23T00:45:47Z

Modules such as net/dsa/dsa_core.ko might want to iterate through an array of compatible strings for things such as validation (or rather, skipping it for some potentially broken drivers). of_device_is_compatible() is exported, by of_device_compatible_match() isn't. Export the latter as well, so we don't have to open-code the iteration. Cc: Frank Rowand Signed-off-by: Vladimir Oltean Acked-by: Rob Herring Signed-off-by: Jakub Kicinski

of: move from strlcpy with unused retval to strscpy

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

of: base: Avoid console probe delay when fw_devlink.strict=1

2022-06-27T14:52:25Z

Commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by default") enabled iommus and dmas dependency enforcement by default. On some systems, this caused the console device's probe to get delayed until the deferred_probe_timeout expires. We need consoles to work as soon as possible, so mark the console device node with FWNODE_FLAG_BEST_EFFORT so that fw_delink knows not to delay the probe of the console device for suppliers without drivers. The driver can then make the decision on where it can probe without those suppliers or defer its probe.
