[PATCH] debug: Add braces around empty body in an 'if' statement

Browse Source 
I have below code in my cc.h:

 #ifdef MYSDK_LWIP_DEBUG
 #define LWIP_PLATFORM_ASSERT(x) MYSDK_ASSERTION_FAIL_ACTION()
 #else
 #define LWIP_PLATFORM_ASSERT(x)
 #endif /* ifdef MYSDK_LWIP_DEBUG */

I got below error when in non-debug build:
src/include/lwip/debug.h:76:32: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
   LWIP_PLATFORM_ASSERT(message); } while(0)
                                ^
Fix the build error by adding braces around empty body in an 'if' statement.
