This patch leads to the following build warnings:

   CC [M]  drivers/staging/rtl8712/rtl871x_security.o
In file included from drivers/staging/rtl8712/osdep_service.h:43:0,
                  from drivers/staging/rtl8712/rtl871x_security.c:45:
drivers/staging/rtl8712/rtl871x_security.c: In function ‘crc32_init’:
drivers/staging/rtl8712/basic_types.h:35:14: warning: ISO C90 forbids mixed 
declarations and code [-Wdeclaration-after-statement]

drivers/staging/rtl8712/rtl871x_security.c:129:2: note: in expansion of macro ‘sint’
   sint i, j;
   ^
The previous code had braces around the code in question. Either you need to 
leave those braces, or you need to move the declarations.

Please compile test your patches!
