Juhan Jin de237129b9 riscv: ftrace: Add parentheses in macro definitions of make_call_t0 and make_call_ra ... [ Upstream commit 5f1a58ed91 ] This patch adds parentheses to parameters caller and callee of macros make_call_t0 and make_call_ra. Every existing invocation of these two macros uses a single variable for each argument, so the absence of the parentheses seems okay. However, future invocations might use more complex expressions as arguments. For example, a future invocation might look like this: make_call_t0(a - b, c, call). Without parentheses in the macro definition, the macro invocation expands to: ... unsigned int offset = (unsigned long) c - (unsigned long) a - b; ... which is clearly wrong. The use of parentheses ensures arguments are correctly evaluated and potentially saves future users of make_call_t0 and make_call_ra debugging trouble.
