Subject: [PATCH v4 1/4] sysfs: Improve readability by following the kernel coding style

The purpose of the if/else block is to select the right sysfs directory
entry to be used for the files creation. At a first look when you have
the file in front of you, it really seems like the "create_files()"
lines right after the block are badly indented and the "else" does not
guard. In practice the code is correct but lacks curly brackets to show
where the big if/else block actually ends. Add these brackets to comply
with the current kernel coding style and to ease the understanding of
the whole logic.
