HID: microsoft: do not use compound literal - fix build
commit 6b90466cfec2a2fe027187d675d8d14217c12d82 upstream. In patch "HID: microsoft: fix invalid rdesc for 3k kbd" I fixed support for MS 3k keyboards. However the added check using memcmp and a compound statement breaks build on architectures where memcmp is a macro with parameters. hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3 On x86_64, memcmp is a function, so I did not see the error.
