%x is not a valid wildcard. Use <x> instead, as this allows script/get_abi.pl to convert it into a regex. Signed-off-by:

An "N" upper letter is not a wildcard, nor can easily be identified by script, specially since the USB sysfs define things like. bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl to convert it into a Regex. Signed-off-by:

On most ABI files, the wildcards are used as <x>, instead of (x). Replace it to make it using a more standard wildcard. That helps get_abi.pl to convert it into a regex. Signed-off-by:

While humans may be able to understand that something like: /sys/bus/rapidio/devices/nn:d:iiii could actually mean: /sys/bus/rapidio/devices/00:e:0000 This is something that computers can't easily identify. As get_abi.pl needs to convert it into a regex, change What: lines to: /sys/bus/rapidio/devices/<nn>:<d>:<iiii> Which is the commonly-used pattern on ABI files for wildcards. Signed-off-by:

There is some debate about whether it's deemed acceptable to call dev_err_probe() if you know that the error code can never be -EPROBE_DEFER. Clarify in the function comments that this is OK. Specifically this makes us able to transform code like this: ret = do_something_that_cant_defer(); if (ret < 0) { dev_err(dev, "The foo failed to bar (%pe)\n", ERR_PTR(ret)); return ret; } to code like this: ret = do_something_that_cant_defer(); if (ret < 0) return dev_err_probe(dev, ret, "The foo failed to bar\n"); It is also possible that in the future folks might want a CONFIG option to strip out all probe error strings to save space (keeping non-probe errors) with the argument that probe errors rarely happen after bringup. Having probe errors reported with a consistent function would allow that.

Contrary to the comment ->show is never called from lseek for sysfs, given that sysfs does not use seq_lseek. So remove the NULL ->show case and just WARN and return an error if some future code path ends up here. Acked-by:

Use the helper macro SET_RUNTIME_PM_OPS() instead of the verbose operators ".runtime_suspend/.runtime_resume", because the SET_RUNTIME_PM_OPS() is a nice helper macro that could be brought in to make code a little clearer, a little more concise. Signed-off-by:

The function kobject_create() is only used by one caller, kobject_create_and_add(), no other driver uses it, nor is exported to other modules. However it's still exported in kobject.h, and can sometimes confuse users of kobject.h. Since all users should call kobject_create_and_add(), or if extra attributes are needed, should alloc the memory manually then call kobject_init_and_add(). Signed-off-by:
