drivers/staging/rtl8192u/TODO

-To-do list:
-
-* Correct the coding style according to Linux guidelines; please read the document
-  at https://www.kernel.org/doc/html/latest/process/coding-style.html.
-* Remove unnecessary debugging/printing macros; for those that are still needed
-  use the proper kernel API (pr_debug(), dev_dbg(), netdev_dbg()).
-* Remove dead code such as unusued functions, variables, fields, etc..
-* Use in-kernel API and remove unnecessary wrappers where possible.
-* Fix bugs due to code that sleeps in atomic context.
-* Remove the HAL layer and migrate its functionality into the relevant parts of
-  the driver.
-* Switch to use LIB80211.
-* Switch to use MAC80211.
-* Switch to use CFG80211.
-* Improve the error handling of various functions, particularly those that use
-  existing kernel APIs.
