Fix a number of misspelled words, and while at it, correct two phrases used
to indicate a status of an operation where words used have been cleverly
truncated and thus always trigger a spellchecking error while performing a
static code analysis over the PCI tree.

- Use sysfs_emit() in "show" functions instead of sprintf() to avoid buffer
overruns (Kunihiko Hayashi)
* remotes/lorenzo/pci/endpoint:
PCI: endpoint: Use sysfs_emit() in "show" functions
|
|
Convert sprintf() in sysfs "show" functions to sysfs_emit() in order to
check for buffer overruns in sysfs outputs.

Most of the "store" functions that handle userspace input via sysfs return
-EINVAL should the value fail validation and/or type conversion. This
error code is a clear message to userspace that the value is not a valid
input.
However, some of the "show" functions return input parsing error codes
as-is, which may be either -EINVAL or -ERANGE. The former would often be
from kstrtobool(), and the latter typically from other kstr*() functions
such as kstrtou8(), kstrtou32(), kstrtoint(), etc.
-EINVAL is commonly returned as the error code to indicate that the value
provided is invalid, but -ERANGE is not very useful in userspace.
Therefore, normalize the return error code to be -EINVAL for when the
validation and/or type conversion fails.

Add virtual function number in pci_epc ops. EPC controller driver
can perform virtual function specific initialization based on the
virtual function number.

Fix kernel-doc formatting errors, function names that don't match the doc,
and some missing parameter documentation. These are reported by:
make W=1 drivers/pci/
No functional change intended.
