[PATCH] staging: rts5208: Fix coding style issues

[Jacob Lott <jklott.git@gmail.com>]

Help text in a module should describe the module and give
some guidance on whether or not to enable it.

The BIT macro should be used instead of 1UL << n. This
makes the code more readable and easier to maintain.
