Revert "NFC: fix attrs checks in netlink interface" This reverts commit18917d5147. Our checks found weird attrs present check in function nfc_genl_dep_link_down() and nfc_genl_llc_get_params(), which are introduced by commit18917d5147("NFC: fix attrs checks in netlink interface"). According to its message, it should add checks for functions nfc_genl_deactivate_target() and nfc_genl_fw_download(). However, it didn't do that. In fact, the expected checks are added by (1) commit385097a367("nfc: Ensure presence of required attributes in the deactivate_target handler") and (2) commit280e3ebdaf("nfc: Ensure presence of NFC_ATTR_FIRMWARE_NAME attribute in nfc_genl_fw_download()"). Perhaps something went wrong. Anyway, the attr NFC_ATTR_TARGET_INDEX is never accessed in callback nfc_genl_dep_link_down() and same for NFC_ATTR_FIRMWARE_NAME and nfc_genl_llc_get_params(). Thus, remove those checks. Signed-off-by: Lin Ma <linma@zju.edu.cn> Link: https://lore.kernel.org/r/20240410034846.167421-1-linma@zju.edu.cn Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
