That's weird.  The original code is valid but it generates a sparse
warning.

drivers/staging/rtl8192u/ieee80211/rtl819x_TSProc.c:244:58: warning: Initializer entry defined twice
drivers/staging/rtl8192u/ieee80211/rtl819x_TSProc.c:244:61:   also defined here

It has something to do with "_Bool" types.  Changing it to "int" will
also make the warning disappear.  I've CC'd the sparse list to see if
anyone knows what's happening.
