INT and SHORT are used by some drivers that pull in the include files, so prefixing helps avoid namespace conflicts. Other constructs in the same file already uses this. Fixes, among others, these warnings with allmodconfig: ../sound/core/pcm_misc.c:43:0: warning: "INT" redefined #define INT __force int Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
