| Subject: [PATCH] util/udma_barrier.h: fix mips4 build |
| |
| The 'sync' instruction for MIPS was defined in MIPS-II as taking no |
| operands. MIPS32 extended the define of 'sync' as taking an optional |
| unsigned 5 bit immediate. |
| |
| As a result, replace "sync 0" by "sync" to fix the following build |
| failure on mips4 raised since version 43.0 and |
| https://github.com/linux-rdma/rdma-core/commit/b7c428344ea96d446f6ffe31c620a238a7f25c9e: |

| /tmp/ccrBy9fV.s: Assembler messages: |
| /tmp/ccrBy9fV.s:994: Error: invalid operands `sync 0' |
