[Qemu-devel] [PATCH v2 2/2] target/mips: add or remove space to fix checkpatch errors

[Jules Irenge]

Add or remove space to fix errors issued by checkpatch.pl tool
"ERROR: spaces required around ..."
"ERROR: space required after that"
"ERROR: space required before the open parenthesis"
"ERROR: space prohibited between function name and open parenthesis"
within "target/mips/cpu.h" file.
