net/wireless: use generic_file_llseek in debugfs
The default llseek operation is changing from default_llseek to no_llseek, so all code relying on the current behaviour needs to make that explicit. The wireless driver infrastructure and some of the drivers make use of generated debugfs files, so they cannot be converted by our script that automatically determines the right operation. All these files use debugfs and they typically rely on simple_read_from_buffer, so the best llseek operation here is generic_file_llseek. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: "John W. Linville" <linville@tuxdriver.com> Cc: linux-wireless@vger.kernel.org Cc: netdev@vger.kernel.org
