We get 2 warnings when building kernel with W=1:
drivers/staging/rtl8192u/r8192U_core.c:925:12: warning: no previous declaration
for 'ieeerate2rtlrate' [-Wmissing-declarations]
drivers/staging/rtl8192u/r8192U_core.c:958:12: warning: no previous declaration
for 'rtl8192_rate2rate' [-Wmissing-declarations]
drivers/staging/rtl8192u/r8192U_core.c:1322:11: warning: no previous
declaration for 'rtl8192_IsWirelessBMode' [-Wmissing-declarations]
In fact, these functions are unused in
r8192U_core.c, but should be removed.
So this patch removes the unused functions.
